Abstract

This study focused on the electrical response of fabricated polyaniline (PAni) to ammonia. PGs were used as working electrodes and directly immersed in an aqueous, aniline-containing electrolyte to fabricate PAni on the surface of these electrodes. The electropolymerization of PAni was carried out by applying three bias currents with different times in succession: 0.06mA, 0.03mA and 0.015mA. SEM images showed sphere-like particles of the sample. Diameter sizes varied from 200nm-1.2µm. FTIR test showed chemical reactions and structures of the sample. Electropolymerized PAni showed electrical response when exposed to ammonia and is linearly dependent on the electropolymerization time of PAni.
