The development in polypyrrole and its copolymer

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.
