Abstract
Poly(3,4-ethylenedioxythiophene)/poly(styrene-4-sulfonate) (PEDOT/PSS) comp osites have been prepared from aqueous and aqueous acetonitrile solutions o f EDOT and NaPSS by oxidation using Fe(III) salts. Powders with PEDOT to PS S ratios ranging from 0.3 to 4.2 and electronic conductivities as high as 1 0 S cm(-1) have been obtained in good yields. The PEDOT/PSS blends are cati on exchangers and exhibit facile electrochemistry in both aqueous and aceto nitrile media. Impedance measurements have shown that 30 mu m thick PEDOT/P SS layers have proton conductivities as high as 0.03 S cm(-1).
