摘要
聚吡咯具有较高的电导率与良好的环境稳定性,被视为继聚苯胺之后最有工业化应用前景的导电高分子材料之一。聚吡咯与常规聚合物基体如聚乙烯醇、聚氯乙烯等形成的复合膜不仅可以综合聚吡咯奇异的多功能性与常规聚合物的易成膜性和低成本性于一体,而且可望发挥两者的协同效应,从而大大拓宽其应用领域。该研究已经成为导电聚合物研究领域中的又一新热点。作者系统论述了这类功能复合膜的两种典型制备方法,并在分析各自特点的基础上提出了改进与发展方向,指出聚吡咯复合膜具有广泛可调的电导率、快速的电学响应性以及稳定的电致变色性等多种功能,在透明导电膜、化学传感器、生物分离膜、电致变色膜领域具有诱人的应用前景。
Polypyrrole has been considered one of the most prospective conducting polymers for industrial applications following polyaniline for its high conductivity and good environmental stability. Composite films from polypyrrole and some conventional polymer matrixes such as poly（vinyl alcohol） and poly（vinyl chloride）, could not only integrate the exciting multifunctionality of polypyrrole as well as the good film-formability and much lower cost of the matrix polymers, but also produce a novel coadjutant effect of both polymers. Therefore these kinds of composite films have widened application fields, and have become a new research hotspot in the fields of conducting polymers. Two typical preparation methods of these conductive polypyrrole composite films have been systematically reviewed. According to careful analysis of their individual characteristics, the possible improvement and development are proposed. Having a variety of excellent functions such as widely-variable electroconductivity, fast electrical response and stable electrochromism, the polypyrrole composite films have shown a great attraction of potential applications in many fields including transparent conducting films, chemical sensors, bioseparation, and electrochromic films.
