▎ 摘　　要

NOVELTY - A polytrimethylene terephthalate/graphene composite manufacturing method involves melt mixing or solution mixing of graphene with polytrimethylene terephthalate, where graphene is obtained by heat-treating natural graphite with acid treatment. USE - Method for manufacturing polytrimethylene terephthalate/graphene composite that is utilized in a fiber, a film and a plastic product (all claimed). ADVANTAGE - The polytrimethylene terephthalate/graphene composite has better mechanical property, thermal stability and electric conductance effect. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation of mechanical property of a polytrimethylene terephthalate/graphene composite. '(Drawing includes non-English language text)'
