Polyaniline Composites Using Three Different Acid as a Secondary Dopant: Preparation and Properties

Abstract:

In this paper, the preparation of PANI was investigated via in secondary doping in-situ chemical oxidation polymerization. We use NH₂SO₃H as dopant, and HP₃O₄, H₂SO₄ or HCl as secondary dopant, respectively. The influencing of products conductivity was discussed about difference secondary dopant with changing concentration. The synthesized polymer composites are characterized by Fourier Transform Infrared Spectroscopy (FTIR) and four probe conductivity apparatus. The results show that in redoping process, the conductivity of PANI was 3.1746 S/cm when the concentration of HCl was 1.0 mol/L. Meanwhile, the thermal stability of PANI prepared with HP₃O₄ or H₂SO₄ as secondary dopant was better than HCl as secondary dopant.
