Preparation and characterization of PEDOT/PSS hybrid with graphene derivative wrapped by water-soluble polymer

Abstract

We conducted investigation on the hybridization of poly(3,4-ethylenedioxythiophene)/poly(styrene sulfonate) (PEDOT: PSS) with graphene derivative (G-PSS), which has been prepared by wrapping reduced graphene oxide (RGO) with PSS. In situ polymerization of PEDOT/PSS in the presence of G-PSS afforded the PEDOT/PSS and graphene hybrid (GP). The analysis of XPS, IR and Raman spectroscopies for GP showed that PEDOT/PSS was successfully synthesized and hybridized with graphene. Compared to the G-PSS, GP showed an enhanced electrical conductivity of 4.46 × 102 S/m with a good wter-dispersity.
