聚酯／棉导电织物在产业用纺织品开发中的创新应用

摘要

The in-situ polymerization of polypyrrole (PPy) on PC blend fabrics was successfully carried out by a 2 step process. The surface resistivity of the samples was obtained in the range of 50 - 2 500Ω/square. The con- ductivity range is suitable for many technical textile applications. The SEM exhibited complete coating of fibers and inter-yarn spaces by the polymer. The durability studies revealed that the aqueous washing resulted in remarkable loss in conductivity. Whereas, dry cleaning was comparatively less severe as conductivity loss was relatively negligible. Further research needs to be focused on improvement of PPy coated textiles towards aqueous washing in order to expand its scope in application areas that demand durability.%在聚酯／棉混纺织物上通过2步法成功实施了聚吡咯的原位聚合，所得样品单位面积的表面电阻率在50～2500Ω。该电导率范围适用于很多产业用纺织品领域。扫描电镜显示，聚合物完全覆盖了纤维和纱线间的空隙。耐久性研究发现，水洗会导致电导率的显著损失。而干洗影响相对较小，电导率损失可相对忽略不计。为了扩展其应用领域，进一步的研究需着重于改善聚吡咯涂层纺织品的耐水洗性。
