Conducting polymers nanocomposite materials have emerged as a critical field of study in contemporary science and technology. Nanoparticles and nanocomposites composed of metals, polymers, carbon nanotubes, because of their optical, mechanical, dielectric, chemical, and magnetic properties, have been used in a huge number of applications. The current work agreements with the study of Dielectric properties of PANI/TiO2, PANI/MWCNT and PANI/TiO2/MWCNT carbon nanocomposites which are prepared by an “In-situ chemical oxidation polymerization of aniline” using ammonium peroxide sulfate (APS) as an oxidant. The dielectric constant value enhanced by 109.21% as observed for PANI/TiO2 composite whereas in PANI/MWCNT composite this improvement observed 134.08%. Moreover, for PANI/TiO2(8wt%)/MWCNT(8wt%) nanocomposites dielectric constant evaluated 157.49% improved with respect to polyaniline (PANI) specimen. The study finds that PANI/TiO2/MWCNT specimens show superior structural and electrical characteristics, making them suitable for research and development in the area of energy storage devices and application.
