Electrochemically sound MWCNT-PANI/Zirconium(IV)molybdate nanocomposite was successfully assimilated via in-situ oxidative polymerization of aniline monomer. The microstructure and morphology of the prepared composites were characterized using several techniques. Electrochemical studies revealed that MWCNT- PANI/Zirconium(IV)molybdate nanocomposite have excitingly higher super capacitance behaviour as compared to PANI/Zirconium(IV)molybdate and MWCNT with enhanced anodic and cathodic current levels (Ipa= 0.386 A and Ipc= 0.080 A). The improved performance of the composites was further validated through Bode plots with phase angles 53°, 48° and 41° for MWCNT-PANI/Zirconium(IV)molybdate, PANI/Zirconium(IV)molybdate and MWCNT respectively. Super capacitance behavior of nanocomposite is attributed mainly to high electrical and thermal conductivity of carbon nanotubes, zirconium (IV) molybdate and polyaniline, high surface area, and stability of the carbon nanotubes. On the whole, the assimilated nanocomposite assures promising aspects for upcoming energy conversion and energy storage devices. Besides this, the synthesized nanocomposite showed an enhanced cytotoxic potential against various human cancer cell lines (HeLa, MCF-7, and Hepa-3B). In-vitro results demonstrated the significant anticancer potential of the composite when compared with MWCNTs and Zirconium (IV) molybdate alone, is due to the synergetic effect of MWCNT with PANI- Zirconium (IV) molybdate
