Abstract
In this study, polyaniline (PANI) was synthesized through oxidative polymerization assisted by sodium dodecylbenzene sulfonate (SDBS) in hydrochloric acid (HCl) concentration solution to investigate the effect of dopants in the electrical conductivity of polyaniline. The polyaniline obtained from the oxidative polymerization was confirmed with FTIR. The x-ray diffraction pattern showed that polyaniline is semi-crystalline. SDBS does not only act as a template for oxidative polymerization but also acts as a dopant. The dielectric constant, the dielectric loss, and the ac conductivity increase as polyaniline is doped with SDBS, HCl, or with both SDBS and HCl.
