Abstract

In our pursuit of a flexible energy storage solution, we have developed biocompatible (bc)-NG/
PVA composite polymers by combining neem tree gum (NG) with polyvinyl alcohol (PVA). This
innovative bio-inspired approach harnesses NG’s unique properties for both the bio-electrolyte
and bio-electrode components. The resulting bc-NG/PVA composites exhibit superior dielectric
strength and versatility, surpassing traditional inorganic ceramic dielectrics in advanced elec�tronics and pulsed power systems. Our study investigates the dielectric characteristics, conduc�tivities, electric modulus, and impedance parameters of Pure PVA and NG-doped PVA composites.
Adding 5 % NG to PVA significantly boosts its conductivity from 10− 8 S cm− 1 to 10− 4 S cm− 1
,
while the dielectric constant of PVA/5 % NG composite jumps to 104.5 compared to pure PVA.
These improvements position the composite films of 5 % NG added PVA as promising materials
for diverse applications. The heightened performance of these NG-blended PVA composite ma�terials underscores their potential as a valuable resource for flexible energy storage solutions.
