New Method for Polymerization of Pyrrole and Its Derivatives. (Reannouncementwith New Availability Information)

摘要

The polymerization of pyrrole could be traced back as early as in 1916, when ablack amorphous powder was obtained by oxidation of pyrrole, and the polymers were referred to as 'pyrrole black' for many years. In the late 1970s and early 1980s, a breakthrough in polypyrrole research came when the polymer was prepared in the form of continuous films by anodic oxidation and was found to have interesting electrochemical properties and a high electronic conductivity. Since then, extensive studies have been carried out on polypyrrole and related derivatives. Using appropriate processing methods, such as stretching of the polymer films or fibers or the intercalative polymerization of pyrrole in an inorganic matrix, the conductivities of polypyrroles were reported to be as high as 500-7500 S/cm. Among many interesting applications, polypyrroles were used recently for the construction of biosensors.
