摘要(Abstract)：

采用热压成型技术制备了热塑性聚氨酯(TPU)薄膜,在二甲苯溶剂中适度溶胀,并于不同浓度的多壁碳纳米管(MWCNTs)溶液中超声修饰制备TPU/MWCNTs导电薄膜.通过绝缘电阻测试仪、万能材料试验机、热失重分析仪(TG)和扫描电子显微镜(SEM)对TPU/MWCNTs薄膜的电性能、力学性能、热稳定性和形态结构进行测试.结果表明:MWCNTs不仅均匀分散于TPU膜表面,而且渗透进入膜内形成完善的导电网络结构,有利于TPU/MWCNTs薄膜导电性能的提高和逾渗值的降低;与纯TPU相比,TPU/MWCNTs薄膜的拉伸强度、杨氏模量和韧性均得到提高;与TPU膜相比,TPU/MWCNTs薄膜的热稳定性提高.
