A cyclic voltammetry study on bi layer and multi layer conducting polymer films

Abstract

Polypyrrole (PPY) is a prime candidate for a polymer actuator; but has the disadvantage that the electronic conductivity decreases by two or three orders of magnitude as the polymer is reduced. This reduces the actuator performance. A Standard way of overcoming this problem is to add Au or Pt layers as thin patterns or as helices on the polymer. The present work is an attempt to use a second more highly conducting polymer, poly(3,4- ethylenedioxythiophene), (PEDOT), to enhance the electronic conductivity.
