This video lecture presents the Zisman method of measuring surface energy of a solid surface. It involves measuring contact angles by homologous liquids (at least three) on the solid surface. Video also presents discussion on the surface energy measurements of magnetic hard disks which contains an ultra thin layer of DLC and PFPE (Z-dol).
