摘　　要：化学氧化溶液聚合法、化学氧化乳液聚合法和电化学氧化聚合法是目前合成聚氯苯胺的主要方法,所得聚氯苯胺具有类似于聚苯胺骨架的大π键共轭结构,氯取代基的存在使其显示出优异的溶解性和敏感的电催化性.其电催化增敏性、电极稳定性等优于无机物和其他导电聚合物,是一种很有发展潜力的新型功能材料,显示出在修饰电极、pH传感器、气体分离膜等领域广阔的应用前景.Three principal ways to synthesize the polychloroanilines such as chemically oxidative solution polymerization, chemically oxidative emulsion polymerization and electrochemical polymerization are concluded. The resulted polychloroanilines possess-conjugated structures like polyaniline backbones. And the presence of chloro-substituted groups accounts for excellent solubility and sensitive electrocatalysis. The polychloroanilines are of stronger catalysis sensitivity and higher stability in modified electrode than inorganic compounds and other conducting polymers. They are new functional materials with great development potential. They can be applied in a wide area such as modified electrode, pH sensor and gas separation memhrane.
