通过对聚苯胺(PAn)薄膜进行质子酸掺杂,并采用溶液浇铸法,制备出了力学性能和电学性能较好的聚苯胺自撑膜.研究了温度、掺杂时间、掺杂剂浓度、成膜溶剂及质子酸种类等因素对聚苯胺掺杂膜的影响.结果表明:有机磺酸掺杂的聚苯胺薄膜具有金属光泽及较高的致密性和较好的韧性.该膜电导率达到19.30S/cm,与分子尺寸较小的盐酸掺杂的聚苯胺薄膜的电导率(12.5S/cm)具有相同的数量级.且其环境稳定性良好,在空气中放置数月后,电导率基本不变.
By polyaniline (PAn) film proton acid doping, and the use of solution casting method, prepared mechanical and electrical properties of polyaniline self-supporting film better. The effects of temperature, doping time, dopant concentration, filming solvents and the species of proton acids on polyaniline doped films were investigated. The results show that organic sulfonic acid doped polyaniline film has the advantages of metallic luster, high density and good toughness. The conductivity of the membrane reached 19.30 S / cm, which was of the same order of magnitude as that of the thin-film hydrochloric acid-doped polyaniline membrane (12.5 S / cm). And its good environmental stability, placed in the air for several months, the conductivity of the same.
