Abstract
Ultrasonic polymerizations at various wave frequencies of 5-20 kHz were used to synthesize polyaniline (PANI) nanofibers. PANI was synthesized using hydrochloric acid (HCl) as a dopant and ammonium persulfate (APS) as an oxidant. The characteristics of PANI based on molecular structure of functional group and morphology were characterized by fourier transform infrared (FTIR) and transmission electron microscopy (TEM). TEM images of PANI nanofiber show a long nanofibers structure with average diameter of ~25 nm. The FTIR spectra were in acceptable range and confirmed the successful formation of PANI. In this study, the polymerization at frequency wave of 20 kHz shows the best overall properties of produced PANI nanofiber.
