Preparation and performance of conducting polymer nanocomposites prepared by chemical vapor-phase polymerization method

A chemical vapor-phase polymerization(VPP)method was employed to prepare conducting composite poly-3,4-ethylenedioxythiophene(PEDOT)/reduced graphene oxide(RGO)film.The samples to be covered with PEDOT are initially coated with a thin layer of oxidant/GO,and this modifying films was transferred to a VPP chamber containing 3,4-ethylenedioxythiophene monomer gas for chemical polymerization.The latter formed PEDOT/GO film was then treated by glucose and highly conductive PEDOT/RGO films was obtained.The conducive results showed that PEDOT/RGO films exhibited conductivity ca.35.3S/cm,which higher than pure PEDOT(17.3S/cm)and PEDOT/GO(14.6S/cm)films.The PEDOT/RGO films showed specific capacitance ca.176.7F/g and kept 84%initial capacitance after 800 cycles,indicating excellent specific capacitance and cycling stability performance.This VPP PEDOT nanocomposites show promising application in supercapacitor and conducting materials.
