the influence of CTAB ,SDS and triton X-100 surfactants on the electrochemical synthesis and growth of poly (m-toluidine )film at the surface of carbon paste electrode spiked with multi -walled carbon nanotube

carbon paste spiked with multi -walled carbon nanotube was used a substrate for electrochemical synthesis of poly m-tluidine . Electropolymerization of m-toluidine was performed by potential cycling in aqueous solution containing 1.0 MH2SO4,0.02Mm-toluidine and 6.0×10 -3 M of each trhree types of surfactants i.e. cetyltrimethylammonium bromide CTAB, sodium dodecylsulfate SDS triton X-100TX-100. the stability of these films prepared at the absence and presence of surfactants was studied in sulfuric acid solution the results show that these surfactants significantly influence the electrochemical behavior reversibility half wave potential and effective surface area of polymeric modified carbon paste electrode spiled with multi-walled carbon nanotube
