聚吡咯及其共聚物的研究进展

The Development in Polypyrrole and Its Copolymer

作为典型的导电高分子材料,聚吡咯具有良好的光、电、磁特性,其应用已经涉及生物传感器、电致变色、防腐等领域,但聚吡咯天然的难溶熔性和难加工性一直制约着它的规模化应用。制备具有良好力学性能和溶解性的导电聚吡咯已经成为该领域的重要研究内容。制备吡咯共聚物是改善和提高其性能的主要方法之一。文中介绍了聚吡咯及其共聚物近年来的研究进展,着重介绍了制备吡咯聚合物的方法,近期报道的新型吡咯共聚物的种类、合成方法,性能特点以及应用领域。

Polypyrrole is one of the typical conductivity polymers,its unique electrical,magnetic and optical characteristics have led to a large number of potential applications such as biosensor,electromagnetic shielding,anti-corrosion,etc.However,the inherently poor solubility in common solvents and the poor mechanical properties constitute major obstacles to an extensive application.At present,the polypyrrole with better mechanical properties,solubility in conmen solvents and conductivity has the major research in this field.An effective approach to improve its properties is to prepare its copolymer.The recent development of the polypyrrole and its copolymer was reviewed in this paper,the synthetic-method,their properties and application of the newer copolymers were introduced in detail.
