A new biomimetic route for the synthesis of a conducting polyaniline (PANI)/lignosulfonate (LGS) complex is presented. Iron (II) tetrasulfophthalocyanine (FeTSPc) is used to polymerize aniline in the presence of a natural polyelectrolytes template, LGS. The effects of pH, concentrations of aniline, LGS, H2O2, and reaction time on polymerization reaction of aniline were studied. The results show that the polymerization of aniline is strongly pH-dependent in this case. A wider range at low pH (1.0~4.0) was required to produce the conducting PANI. The optimal pH value is 1.5. UV–vis absorption, FTIR, elemental analysis, conductivity, cyclic voltammetry, and thermogravimetric analysis studies all confirm the thermally stable and reversible electroactive form of PANI complex.
