摘要

利用紫外可见光谱研究了聚苯胺（ＰＡｎ）在水基胶体分散液中掺杂与脱掺杂过程

证实了ＰＡｎ的掺杂与脱掺杂是完全可逆的过程．当ｐＨ＝３.５时

开始脱掺杂

当ｐＨ＝６.０时

脱掺杂已基本结束．ＰＡｎ颗粒的大小也对紫外光谱有影响．当聚苯胺颗粒尺寸达到纳米量级时（关键词: 聚苯胺;水基胶体分散液;纳米颗粒;复合膜;电导率;兰移

Abstract

Doping and depoping process of PAn in the aqueous dispersions was investigated via the UV vis spectra. The PAn HCl started to dedoped when pH=3.5

the dedoping of PAn HCl was completed when pH=6 0. UV Vis spectra of PAn/PVA blend films was also investigated. It was found that when the size of PAn particles was less than 75～100nm

the absorption bands shifted towards shorter wavelengths compared with that of PAn particles larger than 150～250nm. The conductivity of PAn/PVA blend films depended not only on the PAn content but also the aggregated state of PAn in the blend films.The smaller size of PAn particles led to the lower percolation threshold of PAn/PVA blend films.
