BaTiO_3纤维/PUIPN_s纳米复合体系导电性能研究

Study on Conductive Property of Barium Titanate/Polyurethane Matrix IPNs Nanocomposites

用红外光谱跟踪确定了同步互穿聚合物网络的形成工艺 ,并制成其梯次化复合涂层 ,TEM检测表明两相间的相畴尺寸在纳米级范围内 ;在此基础上 ,以钛酸钡超细纤维对此网络体系进行复合 ,确定偶联剂的加入量及复合工艺 ,测量了不同复合量下材料的电阻率 ,并考察了其伏安特性。此工作可为拓展此类材料的应用领域提供有价值的参考数据。

The forming technics of interpenetrating polymer networks and its gradient systems based on polyurethane matrix are determined using IR techniques by simultaneous polymerization.The TEM results show that the phase range of materials thus obtained are in nanometer scale.Furthermore,the composites of IPNs blends with Barium Titanate fibers are gained and the conductive and mechanical properties are studied in details.
