Synthesis of Conducting Polyaniline Using Compound Oxidant

摘要：

Conductive polyaniline (PANI) was synthesized by the oxidation of aniline with complex oxidant composed of ammonium persulfate ((NH4)2S208) and ascorbic acid (C6H8O6) in a reaction media containing sulfuric acid (H2SO4). The effects of concentration of H2SO4, (NH4)2S208 and (NH4)2S2Os/C6H806 tool ratio on the polymerization of aniline were studied. The optimal polymerization condition was aniline l mol/L, H2SO4 l mol/L, and compound oxidant (mole ratio of (NH4)2S2O8 to C6H8O6 as to 10:1) lmol/L at room temperature without the protection of N2. The conductivity and yield of PANI reach 13.3S/cm and 96.7％, respectively. The structural changes of PANI were measured by FTIR, Raman and XRD. The results indicated that PANI was some crystal and its groups took place red shift.
