Conducting polymer composites of polypyrrole and polyimide

Polymeric composites with conductivities ranging from 1 to 10 S/cm were prepared by electrochemically polymerizing pyrrole in a matrix of polyimide. The polyimide/polypyrrole (PI/PPy) composites were characterized by SEM, TGA, FT-IR and electrical conductivity measurements. The cyclic voltammetry technique was used to determine the electroactivity and the electrochemical properties of PPy and PI/PPy. Copyright © 1996 by Marcel Dekker, Inc
