Abstract
Polyaniline (PANI) was synthesized by using ultrasonic polymerizations at various frequencies of 5 to 20 kHz. PANI was synthesized in the present using hydrochloric acid (HCl) as a dopant and ammonium persulfate (APS) as an oxidant. The characteristics of PANI based on 1H proton, its molecular structure was characterized by using nuclear magnetic resonance (NMR) and at 7-8 ppm confirmed the PANI structure. Thermal characteristics have also been investigated by using differential scanning calorimetry (DSC). Glass transitions temperature (Tg) at about ~100 °C was it is correlated observed due to recrystallization or cross-linking reaction of PANI. The polymerization at frequency wave of 20 kHz shows the best overall properties of produced PANI nanofiber.
