【摘要】：聚苯胺具有良好的导电性和独特的掺杂-解掺杂特性,成为近年来备受关注的导电高分子材料,其特有的抗划伤、抗点蚀和钝化性能使其在金属防腐领域拥有巨大的应用前景。聚苯胺结构中苯环的存在,使得其分子链具有较大刚性,而分子间氢键又导致其难溶、难熔、可加工性能较差,严重制约了聚苯胺的应用。掺杂过程能有效改善聚苯胺的某些性能,或赋予其新的功能,扩展聚苯胺的应用。本文综述了聚苯胺的掺杂方式、掺杂机理、聚苯胺防腐材料的制备方法,以及其在金属防腐领域的应用,展望了聚苯胺的研究和应用前景。
[Abstract]:Polyaniline with good electrical conductivity and unique doping-dedopant characteristics has become the focus of attention in recent years conductive polymer materials its unique scratch resistance. The properties of pitting and passivation make it have a great application prospect in the field of metal anticorrosion. The existence of benzene ring in the structure of Polyaniline makes its molecular chain more rigid, and the hydrogen bond between molecules leads to its insoluble and refractory. The poor processability seriously restricts the application of Polyaniline. The doping process can effectively improve some properties of Polyaniline or endow it with new functions and expand the application of Polyaniline. The doping methods of Polyaniline are reviewed in this paper. The doping mechanism, the preparation method of Polyaniline anticorrosive material and its application in metal anticorrosion field are discussed. The research and application prospect of Polyaniline are prospected.
