▎ 摘　　要

NOVELTY - A graphene oxide-aluminum alloy composite material is prepared by using aluminum alloy as matrix, and adding 1.0-5.0 wt.% graphene oxide and 0.1-1.5 wt.% rare earth powder. USE - Graphene oxide-aluminum alloy composite material (claimed). ADVANTAGE - The composite material has good conductivity and excellent mechanical and physical property due to the addition of graphene oxide to the aluminum alloy matrix. The preparation process is simple and controllable, suitable for industrial production, and has low material preparation cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene oxide-aluminum composite material.
