▎ 摘　　要

NOVELTY - Preparing graphene modified polyoxymethylene composite material comprises mixing modified graphene and polyoxymethylene in a weight ratio of 0.0001-1:1, adding into a reactor, stirring to react at 140-220 degrees C for 0.1-96 hours, discharging, drying at room temperature and molding. USE - The composite material is useful in vehicles, electrical appliances, machineries, precision instruments and building materials. ADVANTAGE - The method: ensures uniform dispersion of graphene; increases improve the interface binding force between the graphene and polyoxymethylene, thus increasing the tensile strength, impact strength and elongation property of the composite material.
