NOVELTY - Graphene oxide/fatty-aromatic copolyester comprises 0.06-0.5 wt.% graphene oxide, 40-65 wt.% aliphatic dihydric alcohol, 32-57 wt.% dibasic acid or dimethyl ester, 0.1-2 wt.% catalyst, and 0.1-1.8 wt.% stabilizing agent. USE - Graphene oxide/fatty-aromatic copolyester (claimed). ADVANTAGE - The graphene oxide/fatty-aromatic copolyester has excellent melting property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene oxide/fatty-aromatic copolyester involves pretreating graphene oxide by ultrasonically dispersing in water for 20-50 minutes, adding aliphatic dihydric alcohol under stirring at 155-180 degrees C, distilling water, obtaining graphene oxide/aliphatic dihydric alcohol solution, carrying out ester exchange reaction by adding dibasic acid or ester to reactor under nitrogen environment, reacting at 170-210 degrees C, and adding catalyst, and carrying out condensation polymerization by adding stabilizing agent, raising temperature to 235-245 degrees C under vacuum of 50-100 Pa, reacting for 3.5-6 hours, and discharging.
