The nano-structured composite coatings,comprising the graphene-oxide( GO) nano-sheets surface modified with poly( 3,4-ethylenedioxythiophene)( PEDOT) nanoparticles,were synthesized by electrochemical deposition. The nanostructures,electronic structures,electrochromic properties of the PEDOT/GO films were characterized with scanning electron microscope,transmission electron microscope,Raman spectroscopy,and X-ray photoelectron spectroscopy. The results show that the hybrid nanostructures on surfaces of the P...
