Abstract:
Polyaniline as a conducting polymer (CP) possess several advantages such as tunable electrical and electronic properties, facile and low-cost synthesis, good electrochemical properties, biocompatibility and environmental stability that make them attractive alternatives to traditional inorganic electronic materials. These advantageous features of CPs have motivated researchers to explore their potential as alternatives to inorganic electronic materials in diverse application fields. Furthermore, the interactions between inorganic semiconductors and conducting polymers can give rise to interesting and unique properties that are distinct from those of the individual components. These synergistic effects can lead to the development of novel hybrid materials with enhanced performance characteristics, opening up new opportunities in various technological domains.
The present investigation highlights the synthesis of polyaniline (PANI) based nanocomposites doped with metal oxide nanoparticles such as CuO, Fe3O4 and Fe2O3&NiO via oxidative polymerization method in acidic medium, using ammonium persulfate (APS) as an oxidant. Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), UV-VIS spectroscopy and Fourier Transform Infrared Spectroscopy (FTIR) measurements were used to characterize the PANI and PANI based nanocomposites. The electrochemical behaviors of the nanocomposites in alkaline media were investigated.
