▎ 摘　　要

NOVELTY - Fluorocarbon-modified graphene oxide microparticles (I) is new. USE - (I) is useful as a coating hydrophobic additive (claimed). ADVANTAGE - (I): has shielding effect, corrosion inhibition, wear reduction and reinforcement effect; and has excellent hydrophobicity. DETAILED DESCRIPTION - Fluorocarbon-modified graphene oxide microparticles of formula (I) is new. Rf = fluorine-containing long-chain alkyl group. INDEPENDENT CLAIMS are also included for: (1) preparation of (I); and (2) use method, comprising (i) refluxing methyl methacrylate, butyl acrylate, acrylic acid used as monomer, polyvinyl alcohol used as dispersant under at 75-80 degrees C to obtain acrylic resin, and (ii) dispersing 2-40 wt.% fluorocarbon-modified graphene oxide microparticles into acrylic resin, blending, ultrasonically dispersing to obtain coating, applying paint on the wooden board, and drying naturally.
