导电聚合物显示多个应用程序在电子潜力巨大,环境和生物医学领域。特别是,聚氨酯用于电磁shields1,在电极的电容去离子作用淡化咸水water4的过程,并在电极electrocardiography2和脑电图monitoring3 electrostimulation5。导电复合材料可以实现紧凑(电影)或多孔层(泡沫),根据过程。聚氨酯,文献报道不同的食谱取决于最终的材料特性。这意味着各种试剂的使用和添加剂,它违背了制造企业关注的趋势减少化工产品和原材料的过程。本研究的目的是导电的工业发展水性聚氨酯,适合铸造泡沫和电影。在这项研究中,聚醚、聚酯和聚碳酸酯聚氨酯和混合使用不同的cross-linkers和导电填料。五个不同的化合物浓度作为cross-linkers比较相似。基于不同载荷的银导电填料。泡沫是通过机械起泡组件用于混合物的电影。 Paper transfer coating process is used to realize both films and foams for testing. Different paper release materials are considered. Surface resistivity is measured by two-point probes method. Results show that the conductivity of the material depends on all the considered variables in different ways. The main contribution is given by the conductive filler loading, with a percolation threshold about 45% wt. The surface resistivity increases about three orders of magnitudes from film to foam. This loss of conductivity can be recovered by increasing the filler loading. The water-based conductive polyurethane prepared in this work, can be successfully realized in porous or compact layers by industrial process manufacturing, with a cost-saving formula using reduced number of components.
