POLYANILINE: SYNTHESIS, CHARACTERIZATION and CATALYTIC PROPERTIES

Abstract

In the present work, the polyaniline was prepared by chemical oxidation. Being a conducting polymer, polyaniline has nanostructure properties, good environmental stability and low toxicity. Different forms of PANI, such as pernigraniline base, leucoemeraldine base, and emeraldine base, have various oxidation states and can be found in various forms of crystals, whose conductivity strongly depends on protonation with organic or inorganic acids. Its robust redox properties make it an easy catalyst for various chemical reactions. The feasibility of the catalyst is due to its ease in preparation, handling and stability. The PANI is prepared and characterization was done using various laboratory procedures. These include X-ray diffraction, Fourier transform infrared spectroscopy, UV spectroscopy, and infrared spectroscopy.
