聚苯胺改性方法的研究进展

Investigative Progress in Modified Methods of Polyaniline

聚苯胺是一种典型的导电聚合物,具有优良的环境稳定性、合成成本低、无毒以及独特的掺杂机制等优点,但因其溶解性能和力学性能较差而限制了它的应用,因此针对聚苯胺的性能缺陷进行改性研究受到了广泛的关注。综述了近年来聚苯胺改性研究的进展,介绍了通过乳液聚合、掺杂有机或无机质子酸、取代衍生物、复合材料等方法来改性聚苯胺的研究成果,并对聚苯胺改性的研究进行了展望。

Polyaniline is a typical conductive polymer with many advantages of excellent environmental stability, low cost, nontoxicity and unique doped mechanism. But its solubility and mechanical behavior are poor, which limit its application. Therefore, polyaniline modification of performance defects has attracted extensive attention. The recent progress in polyaniline modification are reviewed. And the research achivements of the modified polyaniline through emulsion polymerization, doped polyaniline by organic or inorganic proton acid, substituted derivatives, and composite material are introduced. And an outlook of polyaniline modification is simultaneously discussed.
