dc.description.abstract | For the dielectric capacitors, energy density is determined by dielectric constant and electrical breakdown strength of the dielectric materials. Therefore, improving these parameters is essential for achieving high energy density. In this study, several important strategies have been demonstrated for improving dielectric breakdown strength and energy density, including improving crystallinity of polymers, decreasing the defects and voids, increasing the rigidity of amorphous phase and optimizing the intermolecular interactions between polar groups of polymer blends. It has also been found that the introduction of dedicatedly controlled multiple nanoscaled interfaces in composites and grafting of proper amount of polar groups such as hydroxyl groups, can be other effective strategies in the design of new materials with significantly improved polarization and energy storage density. The low-cost and scalable chemical solution deposition methods and the excellent dielectric performance of the PVDF-based hybrid materials suggest that they have great potential for high density energy storage applications | |
