Synthesis and characterization of poly (3-thiophene acetic acid) as a conducting polymer in the presence of surfactants

Abstract

Poly (3-thiophene acetic acid) or P3TAA was synthesized via an oxidation polymerization in the presence of surfactant. Anionic surfactant that has been introduced in this study was Sodium Oodecyl Sulfate. The SOS doped P3TAA form longer conjugated system, possess higher conductivity, higher thermal stability and better solubility. The polymerization process was carried out in aqueous medium containing oxidant and SDS as the dopant. Result of the FT-IR analysis shows the shifting of the absorption frequency and proved that SDS was incorporated into P3T AA as the doping anion.
