I have been after duplicating these same video from 7 years ago for a while now, and thanks to this I know I am on the right track for most of it. Since I do not need to clean out the soap agent, I will be seeing if I can get this to do similar levels with LDPE shreds. I can get shopping bags all day long, so if I can turn them into a high strength material, I can make all kinds of things with it.
Thank you Rob for once again showing us how outside the box thinking can solve some incredibly difficult problems! The moment I saw you mention the uses for graphene powder, it made me think of ROMAN concrete. I was going to ask, now that we know the exact formula for the toughest long lasting Ancient Roman Concrete, would it be possible to reinforce the ancient Roman Formula with graphene powder, for Concrete that can be put to work for DIY dams or seaside projects? It would be self sealing and could withstand the fall of time itself.
Casein is pretty useful on its own. When combined with 4+ layers of linen it makes Linothorax armour as used by the ancient Greeks. Note linen or hemp has to be used rather than cotton because of the microstructure of the vegetable fibres. So-o-o- how would your casein graphene perform?
People have made reproduction linothorax armour and tested with arrows, blades etc, it was used for a long time, it is pretty effective, needs a lot of linen though, but at a time when metal was scarce it did a great job, plus it wasn't as hot as wearing metal in a hot Mediterranean climate, truth is we don't know how many layers, or how it was made, if glues or leather were also part of the layers or if casein was part of the process.
That’s amazing thank you for sharing I had no idea, I was already thinking of making a composite plate from hemp, using 20-40 layer high density hemp weave canvas.. being that hemp has such amazing properties, it is already being held up to Kevlar as a viable replacement but I had no clue this was already done in ancient times, I saw hemp soft armor from ancient Asia but never heard of this ancient composite plate. Also want to look into weaves that spread more energy in more directions, there’s a standard plain weave (2 directions) but there’s also triaxial and quadraxial weaves (3 & 4 directions) which is more costly but drastically stronger with any material, they make triaxial carbon fiber for high strength parts in aerospace and performance racing So my new idea is a bio plastic hemp composite ballistic plate, triaxial weave or quadraxial, every other layer cut tilted to 5 degrees, bioplastic impregnated with graphine powder & microfibers for strength as well as ammonium polyphosphate for flame resistance
In the middle ages leather shields were impregnated with hide glue because that made an extremely though composite, they are incredibly strong and though.
Love the segment rob. Reminds me of my days in science class when we made "milk glue". Can't remember exactly what went into it other than milk but it was tough as nails. It was used to hold air craft together during the war when materials were scarce😮
Borax was added to make a woodworkers glue. Or salt water to make a delicious Mozarella cheese... In the Middle Ages, plain soil was added to make a 'cheese floor', smooth and hard as concrete, and could be polished to a shine.
Wow! Thus could be very useful in so many ways. I wonder about the durability over time, exposure to UV, etc. Thank you for sharing these results with us! You never fail to amaze with your creativity!
They did similar thing on Tech Ingredients channel here on YT a few weeks ago where they made pure graphene then laced some epoxy resin with it. As in this video it was astonishing the small amount they added made a big increase in the material strength under load. Very interesting subject thanks.
I am wondering about increasing strength of epoxy resin for coating plywood in boat building. I think you mentioned adding to resin in a previous video. Anyway, as you probably know there are lots of beaches where coming ashore is not exactly like a tropical beach of pure white soft sand. A lot of places in Florida and the Gulf coast of Texas are sharp oyster or reef zones east to damage a boat’s hull. If this stuff can stop a bullet it can sure add protection to a hull moving at less than 10 knots coming aground. I’m thinking add to epoxy on rudder blade, centreboard and centreboard case. Also wondering about UV aspects. Epoxy has zero UV protection and needs paint or UV varnish out in the sun. I’m in Australia : it’s almost winter but I still need a hat and sunglasses outside during the day. Anyway just amazing videos.
I wonder if you can mix 0.5% of this stuff whit PLA+ and extrude it for printing or if it whould slowly obstruct the nozzle. If some one have a filament extruder it's worth a shoot i think.
I think there already exists plastics with graphene in them, I remember the downside is that it chews on the tip of the extruder (aka, the bit that prints the plastics). But I'm unsure of how well bonded it is as it's not pressed under 2 tons lol
turns out there are loads of academics pappers on this... should have started there. If someones is curius betwen 0.1 and 0.2 are the ideal ratios the load goes up around 45% tensile stenght by 17% and energy absortion to about 12% prety neat.
I remember when you were talking about graphene infused plastic years ago and I'm glad to see another update! I'm curious about the strength testing, specifically I'd be interested in seeing the results, what method was used, which measure of strength shows that it's stronger than steel, etc, and I'm curious as to how much the graphene contributed to that strength. I did a quick search that implied that casein is normally on the order of 100 times lower ultimate tensile strength than steel, so if the graphene improved the strength by a factor of 100 or more then that's huge... Thanks again for sharing all the work you do and I'm looking forward to more updates!
interesting that the process for this plastic is not unlike teflon, where they powder it and press it in a mold while heating in the pressurized mold to get the shape. Seems like making friends with a shop that does machining of plastics could prove useful as you could take the chips and shavings and then grind them up to make the powder that graphene is added to before pressing to get that shape out of any plastic similar, (especially the ones that cant be just heated and flow like we do with 3D printer filament plastics)
I've seen people create home made extrudes for recycling failed 3D prints and print supports, I wonder if you could make a bio-plastic 3D printer filament with this? That might give rise to stronger 3D printed parts (could be useful for wind turbine blades.
Looks like I missed this video 6 days ago. Happy to watch it now though . The reminiscent sound quality of 6 years ago was also apparent . I recall the other plastic enhancement of some years back . I think polystyrene dissolved in acetone with the Graphene also in solution then letting the acetone evaporate away to result in enhanced polyester plate with super tuffness .
Good heavens the durability on that thing genuinely scares me. Does this stuff decay over time? If not, this stuff could probably be used in some long term applications like buildings. Very cool!
The problem for us DIY'ers is the combo of heating + pressure. It takes expensive equipment to do this, and making such equipment is not easy either. I suppose you could use all metal vices to push down on it and heat it in an oven or the like, but I don't think that would do near as good as the equipment in the video, and especially not compared to what industry can use/do. With that said, this material would be very interesting to combine with either carbon fiber, basalt fiber, and/or S2 fiberglass cloths and epoxy composite outer, since I'm pretty sure the casein is not fully waterproof. Encasing the bioplastic composite in an epoxy-fiber composite, should make it even stronger, tougher, and completely waterproof. The bioplastic composite would be an *excellent* bulking agent since casein is pretty low density. Would love to see composite blends between the above for all kinds of things from car panels, skateboards, etc, etc.
Is that basically dried grated cheese with grapevine added... when I have bits of cheese stuck to the pot after making it, it goes incredible hard, so I must remember to wash early. :)
So cool! It's Strange how everything's starting to fall in the place we spent years in this community researching. Graffiti and how to make it and all the sudden. It was like a key was found to the lock and now we can move forward with very interesting projects. The bioplast guy agree has great potential for body armor I will be giving this a go!!
Just a thought someone may be able to explore. Some bio-plastics shrink as they cure. A particular mix of concrete that allowed for a graphene incorporated plastic to cure could maybe be pretensioned by default? Just a thought
I honestly don't think shrinkage is a problem with this specific mix and manufacturing process... It's put under a 20 ton press and is already highly compressed due to that. If we put it in a concrete mold that has the 20 ton force needed to mold, then you still need 20 tons of force to keep the mold in place and get all the product inside. I'm more curious what happens to the conductivity, can this perform like metal in more than one way? What if we press a wire out of this, would it be floppy or would it be brittle, ready to snap when you look at it wrong?
@@Yezpahr Sincerely, either I'm not understanding you, or you're not understanding me? The shrinkage in the case would not be a problem, rather a problem turned into a benefit. It wouldn't have to be this plastic, but any that the graphene would bond to. If part of the curing process would utilize the solvent shed by the plastic curing, maybe, only maybe, it would be possible to have a lattice reinforced concrete. There are many videos on pre and post tensioned concrete and it's benefits, if that is where we're not seeing each other. Kinda a Rupert drop, but a block, and not largely the surface.
The problem with a 3-D printer is that it’s just Layering hot plastic that’s not very dense at all (it can’t) 3-D printer is good for one offs, modeling, and maybe knickknacks here and there that aren’t really anything you need to rely on. They’re good in a pinch, but that’s basically it. If you were really in trouble, we’re just wanted to make an at home robot, toy, or something that you do not mind breaking Sintering metal, Or other composites, is another matter entirely.
@user-um9sl1kj6u It depends on the type of 3D printer. There are a lot of different versions out there that are making fantastic, usable, and long-lasting items... not just trinkets or one-offs.
@@geoffkeller5337 agreed the technology is definitely there, on a consumer level the easily printable polymers with all the qualities we want at a acceptable price is probably a little bit further down the road.👍🏼
I just imagine that this material layered in a strong fiber and resin / epoxy base, formed on a concave curved outside edge mold for a chest plate, would make an excellent dragon scale 🐉 armor, especially for blocking spalling bullet fragments. Spalled Fragments from any bullet can riddle large blood vessels in the arms, neck and face. ☠
My head! It is reeling from too much potential. I’ll be able to start my own Space program soon! Thanks to this Tinkering man, I’ll be on the Moon by the Time I reach 90.
Kitchen science at it's best! How does the Graphene affect the other properties of the plastic? I'm thinking of heat and elasticity. I keep wondering when you are going to run out of twists to "normal" stuff ........ but I guess the answer to that is "Never"! Once again Thanks for all this output!
From Green Tea Graphene about eight years ago, and now Graphene from blood, eggs and milk. Hmm.. if you find somewhere, a way to make Graphene from flour, we can take all the leftovers and have afternoon tea with cakes and blood pudding! 😂 And maybe you'll be known as the Graphene Gourmet! hahahaha! Cheers Robert!
@@draganmiletich3013 Brilliant! 80c for 3 hours seems to do it for the reduction of Graphene Oxide to Graphene! Research revealed that corn powder works too. How about mini potato pancakes and/or corn muffins. Delicious! 👍😄
Thats quite amazing. How does it stand up to different temperatures and water? Could imagine myself casting items out of such a material. If added to epoxy would it be as strong?
Wow I wonde if it can't be pressed onto a sheet of kevlar or something, to make it even stronger, and easy to sew on to a vest, if not I'm sure it can be epoxied on to kevlar, a ship lap pattern would probably do nicely, having a puck 3mm thick on both sides, overlapping with a couple layers of denim and kevlar between you and it, on the back side , looks like it would stop nearly anything you are likely to be hit with!
Could you cast the windmill parts with it? I wasn't sure if that would work because of the press. Thinking along the lines of using the 3d printed parts, maybe printed out of pva fiber as a positive mould to make the negative mould.
I feel so inspired just seeing this, but with an eye to the possible future, and a view of the mistakes we have made in the past; if we had invested in this tech all along, would we have a fix for getting rid of things we had made from it if they were past their most useful? We have the huge problem of plastic waste today because we never thought it through properly. Can we do better this time? I do hope so. This stuff seems so strong, I am not sure how we could go about disposal if needed. Thanks for the insight of course, I am not trying to put any kind of downer on this concept, quite the opposite, just trying to have the answers before others try and spin it away because they have a vested interest in the old polluting petrochem style that is plaguing us right now. Be well. 😉
Would you be willing to produce some in varying thicknesses for some American gun you tubers to test on firing ranges against different hand guns and rifles ?
I just found this channel maybe an hour ago, and was just watching the other video about making graphene in a blender. My main question is, is this bioplastic reformable after initially being made? Would you be able make pellets to use it in injection molding? Im already interested in looking into if i can get makerstock to add some graphene to their plywood so I can cut it easier with my diode laser engraver. Now i have a merhod to make the graphene for that.
Very interesting stuff. How are the elastic properties of this stuff? And do its strength and elasticity properties hold up when it's in thin sheets like steel or aluminum might be used?
Crazy awesome. So we take some milk, boil it, add it to vinegar, separate out the casein. Then mix in graphite with the leftovers and liquidise. Would the vinegar affect the ability of the proteins keeping the graphite granules separated? What size centrifuge would be needed to separate the graphene? Could it just be boiled off? So many questions. It would be worth a few hours of my time trying to find the answers. Thanks!!
So we can make bullet proof vests from milk which is great but how is this linking back to your wind turbines if at all? I really am more interested in your wind turbines but I do find this stuff fascinating as well. 👍
Fire an arrow at it, with a sharp hunting head and a bodkin, see how it compares to kevlar, steel plate, ceramic, a book! Or if feeling really adventurous make linothorax, a bullet and stabproof backpack can be made cheaply with some tiles and a few books, dont test at home children.
