▎ 摘　　要

NOVELTY - A modified white graphene/polyamide composite material comprises 80-100 pts. wt. polyamide resin, 0.5-20 pts. wt. modified white graphene, 0.1-3 pts. wt. antioxidant, and 0.3-3 pts. wt. lubricant. The white graphene is 2-10 layers of white graphene which are subjected to surface lipophilic treatment, and modified by polymerization. USE - Modified white graphene/polyamide composite material used in LED lamp and lamp holder. ADVANTAGE - The modified white graphene/polyamide composite material has high thermal conductivity and toughness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of modified white graphene/polyamide composite material, which involves adding polyamide resin, antioxidant, and lubricant to a high-speed mixer, uniformly mixing, melt-blending, extruding through a twin-screw extruder, pulling, cooling, and air drying.
