▎ 摘 要
NOVELTY - The graphene oxide coating has an inner coating which is set in contact with a substrate. The coating of graphene oxide is evaporated on a metal substrate using evaporation process. The outer coating is set in contact with the surface of the inner coating layer to the external environment. The organic substance is provided with low surface energy coating. USE - Super-hydrophobic graphene oxide coating. ADVANTAGE - The service life is long. The operation of evaporation device is simple. The evaporation device is easy to realize large-scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method for compound roller device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene oxide octyl triethoxy silane modified ultra-hydrophobic coating after testing.
