Conductive and photo-luminescent functionality of reconstituted particle layers prepared from electrodeposited PEDOT films

Overview & Synopsis

Electrodeposited conducting, photoluminescent poly-3,4-ethylenedioxy-thiophene (PEDOT) layers were functionally reconstituted on non-conducting surfaces through spin-coating process. The different electrochemicalmethods, including cyclic voltammetry and potentiostatic deposition on three different oxidation potentials,resulted in chemically invariant PEDOT layers. PEDOT films were removed from conducting electrode surfacesand ultrasonically homogenized before layer reformation on non-conducting support. PEDOT particles haveshown photoluminescent activities both in dispersion and redeposited form. Conductance measurements of thetransferred layers reflected to an ohmic behavior of the reformed films, which exhibited reversible, onemagnitude conductance change upon the change of ambient atmosphere.
