Abstract

Abstract: In this study, polythiophene (PTh) was synthesized by polymerization of thiophene (Th) using the chemical oxidative polymerization method. 4-Amino-1-naphthalenesulfonic acid (Sa) was polymerized through enzymatic polymerization method. After that, conductive polymer mixture was prepared by mixing PTh and PSa. To increase the conductivity of PTh, ionic and nonionic surfactants were used such as sodium dodecyl sulfate (SDS), hexadecyltrimethylammonium bromide (CTAB) and Triton X-100 (Tri-X). The prepared polymer mixtures doped with surfactants were analized by SEM, FTIR spectroscopy, UV–Vis spectroscopy. HOMO-LUMO band gaps, electrochemical properties and electrical conductivity were also analyzed. As a result, it was observed that the conductivity, electrochemical and optical properties of [PTh/PSa] CTAB were better than those of [PTh/PSa]SDS and [PTh/PSa]Tri-X.
