A comparative study on the dc conductivity and optical properties of polyaniline synthesized in different green solvents

In recent years, the development of efficient green chemistry methods for the synthesis of nano particles has become a major focus of researchers. Green synthesis focuses on minimizing the hazard and maximizing the efficiency of any chemical choice. In this work polyaniline (PANI) was synthesized in various green solvent and conventional solvent HCl. The prepared samples were characterized by Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), Thermogravimetry (TG), Scanning Electron Microscopy (SEM), Ultra Violet (UV) analysis and Conductivity studies. The results indicated that the green solvent tamarind juice is more effective for the synthesis of thermally stable emeraldine form of PANI and is competitive in properties with the sample prepared in conventional solvent HCl.
