Abstract

In the pursuit of a flexible energy storage system, we have integrated naturally accessible neem
tree gum with polyvinyl alcohol nanocomposite polymers (bc-Ng/PVA). This bio-inspired
approach leverages the unique properties of neem gum for both the bio-electrolyte and bioelectrode
components. The resulting bc-Ng/PVA nanocomposites exhibit superior dielectric
strength and versatility, outperforming traditional inorganic ceramic dielectrics in advanced
electronics and pulsed power systems. Our study delves into the dielectric characteristics,
conductivities, electric modulus, and impedance parameters of Pure PVA and Ng-doped PVA
composites. The variation in Ng concentration in the matrix leads to notable improvements in
dielectric characteristics and relaxation factors, emphasizing the significance of polymer co-

operative chain segmented movement. We further explore the relaxation time and conductivity
properties of bc-Ng/PVA polymer composite films, showcasing their enhanced electrical and
dielectric properties. The increased performance of these neem gum-blended PVA composite
materials underscores their promise as a valuable resource in the realm of flexible energy storage.
