▎ 摘　　要

NOVELTY - A graphene-modified polypropylene particle comprises 100 pts. wt. polypropylene particle, 0.1-20 pts. wt. single-layer graphene, 0.01-1 pts. wt. antioxidant, 0.1-10 pts. wt. plasticizer, 1-10 pts. wt. light stabilizer, 1-10 pts. wt. lubricant, and 0-40 pts. wt. filler. USE - A graphene-modified polypropylene particle (claimed). ADVANTAGE - Polypropylene particle has high strength and conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-modified polypropylene particle which involves mixing 100 pts. wt. polypropylene particle, 0.1-20 pts. wt. pre-treated single-layer graphene, 0.01-1 pts. wt. antioxidant, 0.1-10 pts. wt. plasticizer, 1-10 pts. wt. light stabilizer, 1-10 pts. wt. lubricant, and 0-40 pts. wt. filler in high-speed mixer, drying in vacuum baking oven, placing dried material into double-screw extruder through metering pump, subjecting to melt-kneading, extruding, and granulating using die head.
