Study on morphology and conductivity behavior of synthesized polyaniline

In the present work, PANI was synthesized by the chemical oxidative method of the aniline in acid medium with ammonium peroxydisulfate (APS) as an oxidant. The structural and morphological study of PANI were characterized using field emission scanning electron microscopy (FESEM) and Fourier transform infrared spectroscopy (FTIR), respectively. The electrical conductivity was measured by applying four probes technique. Moreover, agglomerated morphology was observed at room temperature polymerization from FESEM. Four probe results show better conductivity of PANI at higher polymerization time during the synthesis.
