The present embodiment provides an insight on the fabrication and characterization of polymeric dielectric composites for energy storage applications required in mobile electronic devices, stationary power systems, hybrid electric vehicles and pulse power generation. In present study, conducting carbon particles of appropriate dielectric properties have been selectively functionalized with acrylic resin using micro-ballooning method to form core shell conducting particles in order to tailor its conductivity and dielectric properties (dielectric loss in particular). The core shell conducting particles were then mixed with silicone resin in varied proportions (10, 20, 25 and 30 % wt/wt) to form flexible dielectric micro-composites which exemplify concomitant increase in dielectric constant without impairing dielectric loss owing to selective coating of carbon particles via micro-ballooning method. Formulation containing 25wt% core shell conducting particles showed most linear variation in dielectric constant and dielectric loss factor (tan δ) with respect to frequency due to feeble contribution of interfacial polarization.
