摘　　要：为了改善聚氨酯的力学性能,利用非共价功能化改性的氧化石墨烯对聚氨酯进行改性处理,制备石墨烯/聚氨酯复合材料,并测试了该材料的微观形貌和力学性能。经实验研究发现,在石墨烯所占比例为1.5%的情况下,石墨烯/聚氨酯复合材料的拉伸强度数倍于单纯聚氨酯,但断裂伸长率出现小幅下降,整体力学性能得到显著提升。In order to improve the mechanical property of polyurethanes, we used non-covalent functional modification of graphene oxide to carry out modification of polyurethane treatment, prepared graphene/polyurethane composite materials, and tested the micromorphology and mechanical properties of the material.Experimental studies showed that the tensile strength of 1.5% graphene/polyurethane composites composite materials is several times higher than that of polyurethane alone, but their fracture elongation rate is slightly reduced and the overall mechanics performance is significantly improved.
