以异佛尔酮二异氰酸酯(IPDI)、聚乙二醇(PEG400)、2,2-双羟甲基丙酸(DMPA)和甲基丙烯酸-2-羟乙酯(HEMA)为主要原料合成光固化水性聚氨酯丙烯酸酯预聚体(WPU),再让接枝了硅烷偶联剂KH-570的碳纳米管(CNTs)与该预聚体原位聚合制备WPU/CNTs乳液,加入光引发剂后交联固化得到聚氨酯复合膜.研究了其电学性能和力学性能,通过透射电镜(TEM)对其微观结构进行了分析.结果表明:经过硅烷偶联处理的碳纳米管更均匀地分散在聚氨酯膜中,当CNTs质量分数为0.6％时,复合涂膜的拉伸强度为15.34 MPa,断裂伸长率为30.62％,拉伸模量176.84 MPa,耐冲击强度为10.14 kJ·m-2,涂膜具有半导体性质,可用作抗静电材料.
