聚酰胺(PA)是五大工程塑料中产量最大、用途最广、品种最多的高分子材料,其具有优异的力学性能、良好的耐磨性、自润滑性和较好的耐腐蚀性等,已被广泛应用于汽车、机械、电器、通讯、电子、航天、国防及包装等领域.导电聚合物的导电率覆盖范围从绝缘体到导体,同时具有与金属相似的光、电、磁等性能,所以是极具应用潜力的一类材料.在导电聚合物家族中,聚苯胺因具有较高的导电率、易于合成(化学和电化学合成)、原料易得及电化学性能优良等优点而被广泛研究,
By oxidative coupling polymerization a novel electroactive polyamide, with fixed conjugated length of oligoaniline (amine-capped aniline pentamer ) in the main chain, was successfully synthesized. The structure of the electroactive polyamide was confirmed via FTIR and NMR. The UV-Vis spectra were used to monitor the chemical oxidation process of the reduced polyamide. Moreove, its electrochemical behavior was investigated by cyclic voltammetry(CV) measurement. It was found that the obtained electroactive polyamide with amine-capped aniline pentamer segments had a quasi-reversible electrochemical property in the cyclic voltammetry, which was the same as polyaniline. Its electrical conductivity is about 1.24 × 10^-6 S/cm at room temperature upon preliminarily protonic-doped experiment.
