摘　　要：为了解决石墨烯在铜基体中分散不均匀的问题,采用电荷吸引的方法将带负电荷的氧化石墨烯纳米片均匀的吸附在带正电荷的铜粉的表面,然后用粉末冶金的方法制备石墨烯增强铜基复合材料。采用扫描电镜,透射电镜,拉伸和导热测试等对石墨烯增强铜基复合材料的显微结构,力学性能和导热性能进行了研究。结果表明:石墨烯均匀的分散在铜基复合材料中,石墨烯在基体中的均匀分散和紧密的界面结合有效的提高了复合材料的性能。To solve the agglomeration of graphene in copper matrix composite, graphene oxide sheets with negative charges was homogeneously adsorbed on the surface of Cu powders with positive charges by charge attraction,and then graphene reinforced copper matrix composite was fabricated by powder metallurgy method. Microstructure and properties of the composites were examined by means of scanning electron microscopy,transmission electron microscopy,tensile and thermal conductivity tests. The results show that graphene is homogeneously dispersed in the copper matrix composites. The uniform dispersion and strong interface bonding between graphene and copper matrix lead to the effective improvement of the properties of the composites.
