▎ 摘　　要

NOVELTY - Preparing polyoxymethylene/graphene nanocomposite material comprises dispersing the graphene oxide in the composite solvent, adding amine-based compound, mixing uniformly, adding amino-terminal fluorine-containing polyether and/or hydroxy-terminal fluorine-containing polyether to dispersing uniformly, drying to obtain coupled graphene oxide, mixing polyoxymethylene, antioxidant, and coupled-treated graphene oxide, melting and heating. USE - The composite material is useful in field of aerospace, automotive, electronics and electrical (claimed). ADVANTAGE - The material: has tensile and impact strength; can reach the elongation break to 40-50% and reach the friction coefficient to 0.12-0.2. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for polyoxymethylene/graphene nano composite material is prepared by the above mentioned method.
