聚吡咯导电织物的制备及其性能研究

Fabricated and its performance study of conducting fabrics by polypyrrole deposition process

采用聚吡咯化学气相沉积法和聚吡咯化学液相沉积法制备聚吡咯导电织物,通过实验观察两种方法制备导电织物性能上的区别。研究氧化剂、掺杂剂对导电织物电学性能的影响。结果表明:氧化剂浓度越大,制备的导电织物导电性越好,当浓度增加到一定程度,织物表面比电阻值不随浓度的增加而变小。掺杂剂浓度的变化,对织物表面比电阻值大小影响不是很大。相比之下,采用化学气相法制备的导电织物,织物导电性好,而且纤维表面光滑、均匀,其受刺激的响应灵敏度较好。

Using air-phase polypyrrole deposition process and liquid-phase polypyrrole deposition process fabricate conducting fabrics, research their performance, research the relation between oxidant and doping agent and the electro conductibility. The result： when increasing the consistency of oxidant, the fabric has better conductivity. The consistency reaches the quantity, its influence falls off. To fabric＇s specific surface resistivity , the doping agent concentration change almost makes no difference. The conductivity of conducting fabrics processed by air-phase polypyrrole deposition process is good, the surface of fiber is lubricous, the sensitivity is better.
