摘要: 聚苯胺(Polyaniline,简称PAn)体系作为通用高分子材料已有100多年的历史,但近年来人们发现该体系具有异乎寻常的性质。仅仅经过简单的酸、碱反应,PAn就能从绝缘态变为导电态,且两种状态是可逆的,掺杂剂也只是简单的质子酸、碱,整个过程中体系的电子总数不变,仅发生质子数的增减。

Abstract: The electronic energy bands of poly-m-toluidine(PMT) and polyaniline(PAn) doped before and after with proton acid were calculated by EHMO-COmethod and the atomic charge distribution, valence bands and band gap were made a comparison between PMT and PAn. The effect of substituent has been discussed by quantum chemistry. The calculation results support the hypothesis of electric conducting mechanism of a polaron conduction band.
