ABSTRACT:
Conjugated polymers are doped with ionic dopant species to a preselected room temperature electrical conductivity ranging from that characteristic of semiconductor behavior to that characteristic of metallic behavior, by means of reversible electrochemical doping procedures. The doping procedures are carried out in an electrochemical cell wherein the polymer to be doped is employed as one or both of the electrodes, and the electrolyte is a compound which is ionizable into the ionic dopant species to a p-type material; or if used as the cathode, becomes doped with a cationic dopant species to an n-type material.
