Chemical Synthesis and Chain Structure Characterization of Polyaniline Derivatives

Abstract

导电聚合物已成为较成熟的跨学科综合研究领域。聚苯胺因其简单的合成工艺、特殊的掺杂机制,良好的导电性、环境稳定性及光、电、磁学性能而得到广泛的研究。然而,聚苯胺的在一般溶剂中的难溶性及较差的加工性能限制了其应用范围,为了实现聚苯胺的实际应用,要求在不降低聚苯胺导电性能的同时,改善其溶解加工性能。另外,目前较为常见的苯胺取代基多为给电子基团(如甲基、乙基、甲氧基等),而含有吸电子取代基团的聚苯胺衍生物则少见报道。为此,本论文主要开展了以下三方面的工作:(1)选用了三种不同种类取代基的间位取代苯胺单体,采用乳液聚合法和溶液聚合法合成了三种聚苯胺衍生物:聚间甲氧基苯胺(PmMAn)、聚间溴苯胺(PmB...Conducting polymers are novel organic semi-conducting materials with great promise because of their wide range of potential technological applications. This include their applications in storage batteries, electrochromic devices, light emitting diodes, non-linear optics, as a corrosion inhibitor and in a variety of sensors including chemical and biosensors. Among the conducting polymers, polyanili...学位:理学硕士院系专业:化学化工学院材料科学系_高分子化学与物理学号:20013600
