▎ 摘　　要

NOVELTY - Method for preparing a polyester material loaded with graphene oxide involves (i) grafting acrylic acid onto the surface of polyester material by UV light, so that the surface of the material is negatively charged with carboxyl groups, soaking the negatively charged polyester material in a solution of dopamine, polyethyleneimine or chitosan to form a positively charged coating on the surface of the material through electrostatic action and (ii) soaking the polyester material with a positive surface in a graphene oxide dispersion solution, loading the surface of the material with a negative electric graphene oxide through electrostatic interaction and soaking the negatively charged material in the positively charged cationic solution, so that the surface of the polyester material can be loaded with graphene oxide through layer-by-layer electrostatic self-assembly. USE - The method is useful for preparing a polyester material loaded with graphene oxide. ADVANTAGE - The method can effectively reduce the static water contact angle of the polyester material and improves the hydrophilicity of the material and the adsorption effect on inflammatory cytokines of the material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the polyester material prepared by the method, where the polyester material has an adsorption effect on inflammatory cytokines.
