Polymeric films have received great attention due to ease of processing, flexibility and low cost for capacitor based energy storage devices applications. However, drawback lies in their low dielectric constant. Incorporating high dielectric constant fillers like ceramics within polymers will lead to capacitor devices having high energy storage capacity. Current approaches based on physical blending suffer from the adverse excessive agglomeration of fillers due to the incompatibility of these fillers with the polymer matrix. This project aims to synthesize non-aggregated polymeric/ceramic hybrid materials and develop capacitor based devices utilizing such composite materials. Upon success of the thin-film prototype design; electrical properties, performance and reliability of the device will be studied.
