Abstract:
Conducting polymers have received much attention due to their unique thermal, electrical, optical, conducting, magnetic properties, easy to synthesis process and significant environmental stability. The wide range of electrochemical and optical properties of polyaniline (PANI) along with its excellent stability makes it useful for various applications like super capacitors, sensors, light emitting diodes, solar cells and rechargeable battery etc. In the present study, Its mainly focused to synthesis the conducting polymers of PANI by suitable chemical oxidation method i.e., the oxidation of aniline monomer using ammonium peroxy disulphide (oxidizing agent) along with three different organic acids dopant namely salicylic acid, benzoic acid and oxalic acid respectively. The synthesized PANI doped organic acids compound were structurally characterized by electrochemical and optical studies. The electrochemical characterization was performed by cyclic voltammetry and the optical properties were investigated by UV–vis., spectroscopy analysis. From the cyclic voltammetry analysis, the PANI compounds show well resolved oxidation and reduction peaks which indicate that the synthesized PANI was emeraldine salt form in nature. Moreover the UV–vis., absorption spectra show that the well defined absorption bands in three different organic acids doped PANI samples. Moreover, the obtained spectral studies indicate that the PANI compounds show significant applications in the field of electronic device fabrication.
