NOVELTY - Preparing film comprises taking dimethyl siloxane monomer and corresponding dimethyl siloxane curing agent, mixing, stirring to obtain initial product A, coating initial product A on different substrates, then pressing graphene sheet for on the substrate coated with initial product A, carrying out high temperature curing to obtain intermediate product B, then taking initial product A and dispersing in equal amount of heptane solvent to obtain 5-2000 mg/ml solution, immersing in intermediate product B and taking out, and carrying out high temperature curing to obtain final product. USE - The method is useful for preparing film with super hydrophobic, abrasion-resistant and electrically conductive and self cleaning functions. ADVANTAGE - The film: has super hydrophobic, abrasion-resistant, electrically conductive and has self cleaning functions (all claimed). DETAILED DESCRIPTION - Preparing film comprises taking dimethyl siloxane monomer and corresponding dimethyl siloxane curing agent according to a mass ratio of 10:1-5:2, mixing, uniformly stirring to obtain initial product A, then using rotary coating or scrape coating methods, coating initial product A on different substrates, then pressing graphene sheet for on the substrate coated with initial product A, carrying out high temperature curing to obtain intermediate product B, then taking initial product A and dispersing in equal amount of heptane solvent to obtain 5-2000 mg/ml solution, immersing in intermediate product B and taking out, and carrying out high temperature curing to obtain final product.
