聚苯胺是一种非常有前途的导电聚合物。掺杂能提高聚苯胺的导电性、稳定性及其他性能,聚苯胺的掺杂受到了人们的广泛关注,尤其是有机酸的掺杂。有机酸种类众多且性能各异,能够使聚苯胺很多性质发生变化。本文重点综述了分别以单一有机酸、有机酸和金属氧化物、有机酸和无机酸、有机酸和其他无机物为掺杂剂合成聚苯胺的研究现状,详细介绍了各种掺杂态聚苯胺的性能及应用,简要介绍了影响聚苯胺性能的因素,并比较了不同掺杂态聚苯胺的优缺点。分析结果表明：与单一有机酸掺杂的聚苯胺相比,采用两种类型的掺杂剂共掺杂合成的聚苯胺具有更突出的性能及更大的应用前景。提出了采用两种或两种以上不同类型的掺杂剂共掺杂将是聚苯胺今后的主要研究方向。
Polyaniline is one of the most promising conducting polymers,and doping can improve its electrical conductivity,stability and other properties. Therefore,more and more attention has been paid to the doping of the polyaniline,especially with organic acid. There are many kinds organic acid that have different abilities to change many properties of polyaniline. Research progresses about the polyaniline doped by single organic acid,organic acid and metal oxide,organic acid and inorganic acid,organic acid and other inorganic substance were discussed in this paper. The properties and applications of various kinds of doped polyaniline were presented in detail and the affecting factors on the properties of doped polyaniline were also summarized. The advantages and disadvantages of doped polyaniline were compared. Compared with the single organic acid doping,polyaniline doped with co-dopants have more outstanding properties and broader applications. This paper proposed that co-doping of polyaniline with two or more different kinds of dopants is the main research direction in the future.
