Multifunctional cotton fabric was successfully fabricated by coating graphene oxide (GO) solution dispersion on the surface via vacuum filtration deposition method,and then assembled with polyaniline (PANI) on the surface by in-situ chemical polymerization method.To investigate the structures and morphology,control cotton,GO-cotton,PANI-cotton and PANI-GO-cotton have been characterized by means of FTIR and SEM.And the results conformed the successful formation of GO and PANI on the fabric substrate,also the morphology of the modified fabric illustrated that GO help to enhance the uniformity of aniline polymerization on the surface of PANI-GO-cotton fabrics.
