▎ 摘 要
NOVELTY - Preparing electric conduction composite material comprises soaking graphene micro-chip and ultra-high molecular weight polyethylene powder using ethyl alcohol, using ultrasonic wave cell smashing device for ultrasonically dispersing, forming an uniformly distributed suspension, filtering and vacuum drying to remove alcohol solvent, uniformly attaching the graphene microchip to the surface of the ultra-high molecular weight polyethylene particle, molding, and cooling to room temperature at constant pressure to obtain wafer raw material. USE - The method is useful for preparing electric conduction composite material (claimed). ADVANTAGE - The method is simple and easy process. The composite material: has complete and stable conductive network structure; greatly reduces percolation threshold value of the material; and has highest peak resistivity and relatively low resistivity at room temperature.
