▎ 摘　　要

NOVELTY - Preparing graphene modified polyester composite material based on liquid phase stripping, comprises (i) taking the graphite derivative as raw material, dispersing in the organic solvent, adding dispersant, and preparing graphene dispersion liquid under ultrasonic auxiliary action, and (ii) mixing the graphene dispersion with the polyester monomer, mixing the catalyst, and firstly performing esterification reaction and polycondensation reaction. USE - The method is useful for preparing graphene modified polyester composite material based on liquid phase stripping. ADVANTAGE - The method reduces agglomeration phenomenon of graphene after liquid phase stripping, improves stability and integrity of graphene, and increases uniform dispersibility of graphene in the modified polyester composite material.
