Formation of Gold Nanoparticles During the Vapor Phase Oxidative Polymerization of EDOT Using HAuCl₄ Oxidant

Abstract

The thin layer of poly(3, 4-ethylenedioxythiophene) (PEDOT) on the PET film was obtained by a vapor-phase polymerization technique using HAuCl₄ as an oxidant. The EDOT monomer was easily oxidized by the HAuCl₄ oxidant while HAuCl₄ was reduced to form metallic Au nanoparticles. The formation of PEDOT/Au composite film was monitored by UV-vis spectra and SEM, and the formation of metallic Au was confirmed by EDAX and XPS.
