  • Dry coating processes for substrates
    Patent number: 8691324
    Abstract: Disclosed herein are solvent free, dry coating processes for applying a layered material such as graphene, nanoplate graphite, etc., to a substrate. The applied layered material is devoid of any dispersant and substantially uniform in thickness. Generally, a layered material precursor composition is mixed with a milling medium so that the milling medium is coated with the layered material. The substrate is then contacted with the coated milling medium. The layered material on the milling medium transfers to the substrate to form a coating on the substrate. Such processes may be especially useful for applying conductive films onto a polymeric substrate without the need for additives such as a surfactant or a polymeric binder.
