NOVELTY - Preparing an oxidation-graphene composite film with hydrophobic two-dimensional pore canal, involves (a) dispersing single-layer oxidized graphene powder in water solution, adding organic silane monomer, stirring aggregate at a certain temperature to obtain a GO-silane casting film liquid, (b) dropping the GO-silylane pouring film liquid on a base film, naturally depositing film, and (c) depositing the substrate as a film with an one-dimensionalpore canal. USE - The method of oxidation-graphene composite film with hydrophobic two-dimensional pore canal used for gate control and in membrane separation. ADVANTAGE - The method is simple, stable structure, high selectivity, high-throughput oxidation graphene the composite film with hydrophobic two-dimensional pore canal, uses the organic silane monomer as cross-linking agent, and the monomer can aggregate acid or high temperature catalyzing, grows oligomer on the solid surface forming liquid-like coating and solid surface has good hydrophobicity and sliding property, and promotes fluid transmission.
