▎ 摘　　要

NOVELTY - A graphene/polyester nanocomposite material comprises polyester and monolayer graphene sheets, which are uniformly dispersed in polyester. The surface of graphene sheet is connected with polyester molecules through covalent bond. The polyester molecules are chosen from polytrimethylene terephthalate, polybutylene terephthalate and/or poly(1,4-cyclohexanedimethylene terephthalate). USE - The graphene/polyester nanocomposite material is useful for preparing continuous spinning and functional fabric. ADVANTAGE - The graphene/polyester nanocomposite material has excellent performance, UV resistance, conductivity and mechanical properties, and can be prepared with high production efficiency in a simple and economical manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene/polyester nanocomposite material, which involves: (1) drying monolayer graphene oxide dispersion liquid with size of 1-50 mu m by atomization drying method to obtain pleated spherical graphene oxide, where the carbon-oxygen ratio of pleated spherical graphene oxide is 2.5-5; (2) fully mixing and stirring 100 pts. wt. terephthalic acid, 50-150 pts. wt. diol and 0.01-0.5 pts. wt. catalyst, and carrying out esterification reaction at 200-260 degrees C until no water is generated; and (3) adding 0.02-10 pts. wt. pleated spherical graphene oxide obtained in step (1) and 0.01-1 pt. wt. catalyst to esterification product obtained in step (2), carrying out heat preservation and stirring for 1-3 hours, then heating at 240-310 degrees C, vacuumizing, carrying out reaction until the system is not heated, cooling with water, and carrying out granulation to obtain product.
