▎ 摘　　要

NOVELTY - Graphene paper prepared by chemical modification of laser-induced graphene paper, is claimed. The laser-induced graphene paper is prepared by laser-induced reduction of polyimide paper, using modification reagent in the chemical modification treatment is a fluorosilane solution, where the concentration of the fluorosilane in the modification reagent is 0.2-3 vol.%, the contact angle of the graphene paper capable of continuously adjusting the wettability of multiple liquids to the liquid is 0-155 degrees , and the surface tension of the liquid is 23.8-72.8 mN/m. USE - The graphene paper is useful in device capable of adjusting the surface wettability, as anti-oil pollution material, and windproof material in oil or an oil-oil interface stabilizing material (all claimed). ADVANTAGE - The paper: has good use stability, stretching, rotating, heating and friction test, and exhibits good infiltration stability.
