摘　　要：利用改进的Hummers法制备氧化石墨烯(GO),通过溶液共混的方式制备聚醚酰亚胺/氧化石墨烯(PEI/GO)复合材料。采用XRD、FT-IR、AFM、拉伸、TGA等手段对其结构和性能进行研究。结果表明,当氧化石墨烯含量为质量分数0.3%时,复合材料的拉伸强度提高了41.7%;氧化石墨烯的加入,增强了复合材料的电导性和热稳定性。We synthesized graphene oxide （GO）by modified Hummers＇ method, and subsequently synthesized the polyetherimide/graphene oxide（ PEI/GO） composites by solution blending. The structure and the property of the nanocomposites were analyzed by means of XRD, FT-IR, AFM, Tensile tester and TGA. The results showed that when graphene oxide content reached 0.3wt% ,the tensile strength of the composites increased by 41.7%. Graphene oxide was added to improve the electrical conductivity and the thermal stability of the composite material.
