▎ 摘　　要

NOVELTY - A polymer-graphene mixture is prepared by placing 0.1-10 wt.% graphite powder and polymer powder in solvent medium, magnetically stirring or ultrasonically dispersing, filtering, drying to obtain polymer-graphite powder premix, ball-milling, and stripping in which graphite powder is crystalline flake graphite, earthy graphite, expandable graphite, expanded graphite, highly oriented graphite, and/or pyrolytic graphite, and polymer is polyethylene, polypropylene, polystyrene, polyvinyl chloride, chlorinated polyethylene, chlorinated polyvinyl chloride, and/or polytetrafluoroethylene. USE - Preparation of polymer-graphene mixture (claimed). ADVANTAGE - Preparation process is simple and environment-friendly, product has high quality, and raw material is non-toxic, low cost, and does not dissolve or swell polymer solvent. DETAILED DESCRIPTION - A polymer-graphene mixture is prepared by placing 0.1-10 wt.% graphite powder and polymer powder in solvent medium, magnetically stirring or ultrasonically dispersing, filtering, drying to obtain polymer-graphite powder premix, ball-milling, and stripping in which graphite powder is crystalline flake graphite, earthy graphite, expandable graphite, expanded graphite, highly oriented graphite, and/or pyrolytic graphite, and polymer is polyethylene, polypropylene, polystyrene, polyvinyl chloride, chlorinated polyethylene, chlorinated polyvinyl chloride, polytetrafluoroethylene, polycarbonate, nylon, polyformaldehyde, polystyrene-acrylonitrile copolymer, polystyrene-butadiene-acrylonitrile copolymer, polysulfone, polyethylene terephthalate, polybutylene terephthalate, polyphenylene sulfide, polyether ketone, melamine-formaldehyde resin, and/or phenolic resin. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram for preparation of polymer-graphene mixture. (Drawing includes non-English language text).
