Thermal Stability and Electrical Properties of Polyaniline Synthesized by Oxidative Polymerization Method

Conducting Polyaniline (PANI) was prepared using oxidative polymerization method by using surfactant sodium dodecyl sulfate (SDS), dodecyl benzene sulfonic acid (DBSA) with dopant hydrochloric acid (HCl). Samples were characterized by X-ray diffraction (XRD), Raman Spectroscopy, thermogravimetric analysis (TGA) and electrical conductivity. XRD confirms the formation of PANI-SDS and PANI-DBSA. It also shows its high degree of crystallinity. Raman spectroscopy results confirm emeraldine form of PANI. Electrical measurements indicate conducting nature of PANI. Thermal degradation of synthesized material starts after 100 degrees C.
