Patterning and Conductivity Modulation of Conductive Polymers by UV Light Exposure
Source abstract
Abstract
A novel patterning technique of conductive polymers produced by vapor phase polymerization is demonstrated. The method involves exposing an oxidant film to UV light which changes the local chemical environment of the oxidant and subsequently the polymerization kinetics. This procedure is used to control the conductivity in the conjugated polymer poly(3,4‐ethylenedioxythiophene):tosylate by more than six orders of magnitude in addition to producing high‐resolution patterns and optical gradients. The mechanism behind the modulation in the polymerization kinetics by UV light irradiation as well as the properties of the resulting polymer are investigated.
