Conductive polyanilines doped with di-2-ethylhexylsulfosuccinic acid (DEHSSA) were synthesized in different inorganic acids through emulsion polymerization. A comparison of secondary doping effect by m-cresol on the backbone conformation of the polyaniline and electrical conductivity of these samples were performed. The conductivity increases with increasing m-cresol and the highest conductivity obtained was 384 S/cm for DEHSSA-doped PANI synthesized in hydrochloric acid (HCl).
