摘　　要：目的以十八烷基胺(ODA)修饰的氧化石墨烯(GO-ODA)和热塑性聚氨酯(TPU)为主要材料,制备具有良好导电性能的复合材料。方法采用溶液浇注法与热压工艺制备热塑性聚氨酯/功能化石墨烯(TPU/GO-ODA)复合材料,考察GO-ODA的结构和导电性能,分析GO-ODA对TPU/GO-ODA复合材料的导电性能、拉伸-电阻敏感性的影响。结果 GO-ODA的导电性能明显优于GO;所制备的TPU/GO-ODA复合材料具有良好的导电性能,且它的拉伸-电阻敏感行为可重复性良好。结论 TPU/GO-ODA具有良好的导电性能、应变响应能力和可重复性。The work aims to prepare the composites with good conductivity by taking the graphene oxide modified by octadecylamine（ODA）（GO-ODA） and thermoplastic polyurethane（TPU） as the main materials. The thermoplastic polyurethane/functionalized graphene（TPU/GO-ODA） composites were prepared by solution casting and hot pressing process. The structure and conductivity of GO-ODA were investigated and the effects of GO-ODA on the conductivity and tension-resistance sensitivity of TPU/GO-ODA composites were analyzed. The results showed that the conductivity of GO-ODA was obviously superior to GO; the TPU/GO-ODA composites prepared were of good conductivity, and their tension-resistance sensing behaviors were of good repeatability. TPU/GO-ODA has good conductivity, strain response capacity and repeatability.
