Abstract
This research examines the synthesis of Co(3)O(4)-MWCNTs nano-hybrid structures and their incorporation into PVDF polymer nanocomposite thin films via the solution casting method. The study comprehensively characterizes the structural, thermal, and electrical properties of the resulting nanocomposites using techniques such as SEM, XRD, FTIR, TGA, TDA, DSC, and impedance spectroscopy. XRD confirmed the crystalline structure and phase transition of the PVDF/Co(3)O(4)-MWCNTs nanocomposites, while FTIR analysis revealed the presence of α- and β-phases of PVDF. TGA, TDA, and DSC results revealed enhanced thermal stability, highlighting the potential for high-temperature applications. Notably, the dielectric properties significantly improved at 0.5 wt% Co(3)O(4) and 0.3 wt% MWCNTs. The electrical conductivity of the nanocomposites increased with higher nano-hybrid content, owing to strong interactions between the PVDF polymer and nano-fillers. This work provides insight into the development of advanced nanocomposites with superior thermal and electrical properties, which could be used in electronic and energy storage devices. The novelty of this study lies in the effective combination of Co(3)O(4) and MWCNTs to enhance the properties of PVDF, offering a promising material for future industrial applications.
