摘要：

Study of the effects of evaporation time and oxidant concentration on the polymerization rate and final thickness of poly(3,4-ethylenedioxythiophene) (PEDOT) films found that the polymerization was chemical reaction limited, and that the final film thickness was linearly dependent on oxidant concentration. The influence of spin-coated iron(III) p-toluenesulfonate hexahydrate (Fe(PTS)(3)) oxidant solution on the polymerization and resulting PEDOT structures was also investigated. Spin-coated low-density (1.35 g/cm(3)) Fe(PTS)(3) oxidant solution, consisting of highly anisotropic paracystalline structures, provided open frameworks for the growth of conducting polymers, leading to a-axis oriented paracrystalline PEDOT films. Polymerization proceeded through the oxidant framework, increasing the density of PEDOT-filled oxidant solution to 2.01 g/cm(3) with negligible change of thickness. Furthermore, the formation of a surface organic layer, as a result of spinning, promoted uniform and smooth PEDOT films. Crown Copyright (C) 2011 Published by Elsevier B.V. All rights reserved.
