Polymer dielectrics are highlighted as capable energy storing materials due to their better dielectric strength and supreme versatility compared to inorganic ceramic dielectrics in sophisticated electronics and pulsed power systems. The capacity of pristine polymers to store energy, on the other hand, has hardly been constrained by relatively poor internal dielectric properties. This study demonstrates a viable solution-casting method for creating a MoO3 (0%, 1%, 3%, and 5%) doped PVA-based composites for notable dielectric characteristics. The structural variations and morphological properties in the presence of MoO3 nanoparticles within the polymer, connected through intra/intermolecular hydrogen bonding are investigated using XRD and FTIR. The influence of MoO3 content on the complex dielectric properties, conductivities, electric modulus, and impedance parameters of PVA is further investigated. According to the MoO3 proportion in the host matrix, the dielectric properties and relaxation factors associated with polymer cooperative chain segmental migration alter considerably. The improved electrical and dielectric properties of MoO3 doped PVA composite demonstrate its potential in creating compact polymer electrolyte systems.
