▎ 摘　　要

NOVELTY - A graphene oxide-based carbon fiber surface treatment agent comprises 100 pts. wt. epoxy resin, 50-200 pts. wt. acetone and 0.05-5 pts. wt. graphene oxide. USE - Graphene oxide-based carbon fiber surface treatment agent. ADVANTAGE - The graphene oxide-based carbon fiber surface treatment agent enhances the interfacial adhesion between the carbon fiber and the resin matrix, and is prepared by convenient operation and simple equipment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for processing graphene oxide-based carbon fiber surface treatment agent, which involves (1) preparing carbon fiber surface treatment agent and (2) sizing the treated carbon fiber surface.
