NOVELTY - Polylactic acid/PTW wire comprises polylactic acid, ethylene-butyl acrylate-glycidyl methacrylate copolymer, graphene oxide and compatibilizer. USE - The wire is useful for 3D printing (claimed). ADVANTAGE - The wire has good conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the polylactic acid/PTW wire, comprising dissolving 1-10 pts. wt. graphene oxide and 70-95 pts. wt. polylactic acid in the same solvent, mixing the two solutions to obtain a graphene oxide/polylactic acid dispersion, adding 0.1-30 pts. wt. reducing agent to reduce the dispersion to obtain a graphene oxide/polylactic acid complex material, mixing the graphene oxide/polylactic acid complex material, 5-30 pts. wt. ethylene-butyl acrylate-glycidyl methacrylate copolymer and 1-3 pts. wt. compatibilizing agent by a high-mixer and subjecting to twin-screw modification and granulation.
