Characterization of Polyaniline for Optical and Electrical Properties

Abstract

Semiconductors have the conducting properties in between conductors and insulators. They have wide range of applications in the field of electronics and communications. Silicon compounds are mainly used as semiconducting materials, but the method of production is costly. Hence, the organic semiconductors can be considered, because of cheap raw materials for synthesis and their mode of construction or design. The organic semiconductors like polyaniline (Pani) can be considered because of its aromatic ring and lone pair of electrons on nitrogen for conducting electricity. It is a cheap, easily synthesizable and environmentally stable compound, with exciting electrochemical, optical and electrical properties. The synthesis was done by oxidation of aniline using hydrochloric acid and ammonium persulphate (APS), which forms an emeraldine salt. It was characterized by FT-IR, XRD, SEM NIR and UV-Vis Spectrophotometer.
