Abstract :The tremendous interest for robust, clean energy storage devices to comprehend the growing needs of modern gadgets has led to exploration of materials having unprecedented electrochemical and interfacial properties. Here, the present study deals with the synergistic effects of multi walled carbon nanotubes and polyaniline nanocomposites on the electro-chemical and thermal properties for wide-range of applications. The microstructural, structural, and optical characterizations have been evaluated through scanning electron microscopy insert ignore into journalissuearticles values(SEM);, transmission electron microscopy insert ignore into journalissuearticles values(TEM);, X-ray diffraction insert ignore into journalissuearticles values(XRD);, Fourier transform infrared spectroscopy insert ignore into journalissuearticles values(FTIR);, and UV-Vis spectrophotometry. The thermal stability of the product was also studied through thermal gravimetric analysis insert ignore into journalissuearticles values(TGA); and the room temperature electrical conductivity was also measured. An exceptional enhancement in thermal stability and conductivity has been observed apparently due to interfacial properties of polyaniline insert ignore into journalissuearticles values(PANI); and multiwalled carbon nanotubes insert ignore into journalissuearticles values(MWCNTs);. Further, in present study we are going to report a comparative analysis of thermal and electrical properties of PANI/MWCNT nanocomposites with different loadings of MWCNTs. The room temperature conductivity as calculated for 1%, 2%, 4% and 8% MWCNT loading is around 2.019, 3.075, 4.48, 8.73 S/cm respectively. The mechanism for thermal and electrical enhancements in PANI-coated MWCNT nanocomposites is also expounded.
