Chemical Synthesis and Characterization of Polyaniline for Supercapacitors Application
Abstract: Various polyaniline (PANI) synthesis methods are reported in the literature, depending on the experimental parameters involved (T, t, doping, and mixing procedure). Herein, three chemical polymerization methods were used to synthesis PANI from aniline monomer: rapid oxidation (OR), controlled oxidation (CO), and interfacial oxidation (OI). The PANI was therefore deposited next by drop casting on a silicon (Si) substrate. X-ray diffraction, Raman spectroscopy, and scanning electron microscopy were used to …
