▎ 摘　　要

NOVELTY - Graphene-nano lanthanum oxide-PTFE composite material, comprises 75-85 pts. wt. PTFE, 8-12 pts. wt. graphene-nano lanthanum oxide composite material and 4-8 pts. wt. silane coupling agent. The preparation method of the graphene-nano lanthanum oxide composite material comprises adding nano lanthanum oxide to ethanol solution, uniformly mixing, to obtain nano lanthanum oxide-ethanol solution; adding dispersant to the nano-lanthanum oxide-ethanol solution, stirring to obtain a dispersion, adding graphene to the dispersion, stirring, adding graphene, ultrasonically treating, cooling to room temperature to isolate the solid product, and drying the solid product. USE - The composite material is used for children toy. ADVANTAGE - The graphene-nanometer lanthanum oxide-PTFE composite material has low coefficient of coefficient of friction and high bending strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the graphene-nano lanthanum oxide-PTFE composite material.
