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,以三乙醇胺中和后,原位引入经浓硝酸处理过的碳纳米管(CNTs),制备了光固化水性聚氨酯碳纳米管复合乳液(WPU/CNTs),加入光引发剂后交联固化得到聚氨酯复合膜.研究了复合涂膜的电学和力学性能,通过扫描电镜(SEM)对复合膜微观结构进行了分析.结果表明,碳纳米管均匀分散在聚氨酯膜中,当CNTs质量分数为0.6％时,复合涂膜的拉伸强度为15.54 MPa,断裂伸长率为31.27％,附着力0～1级,悬臂梁冲击强度10.37 kJ/m2.涂膜具有半导体性质,可用作抗静电材料.
