Role and Prospects of Polymer-Based Nanomaterials in the Dielectric World

The development of reliable energy storageEnergy storage systems is the best strategy to resolve the global crisis of increased energyEnergy consumption in this modern high-tech world and exhaustion of fossil fuels for energyEnergy production. Electrostatic capacitors are one of the extensively used energy storageEnergy storage systems by the engineers and researchers among other such devices like supercapacitorsSuper capacitor and batteriesBatteries due to its unique characteristics of superior charge density, ultrafast charge and discharge, high stability, and long-life time. These unique features made them suitable for distributed power systems, microelectronic circuits, electric vehicles, etc. But these electrostatic capacitors have the demerits of low energy densityEnergy density. Therefore, the main objective of researchers is now to achieve high energy densityEnergy density and energy storageEnergy storage efficiency along with the high-power density. The only possible way to attain the high energy densityEnergy density of the electrostatic capacitor is to tailor the features of dielectric materialsDielectric materials. Both the ceramics and polymersPolymer were used individually in the dielectricDielectrics layer of the electrostatic capacitors, while the both the individuals have some pros and cons. So, materials scientist combines both the ceramics and polymerPolymer to obtain the pro qualities of polymerPolymer like high breakdown strengthBreakdown strength and flexibility, and high dielectricDielectrics constant of ceramics. Recently, ceramics in nanoform are chosen as the fillerFiller materials to the polymer matrixPolymer matrix in the trend of device miniaturization. So, in this chapter, we will discuss about the various attempts made to design the polymerPolymer-ceramic nanocompositesNanocomposites to obtain the high dielectricDielectrics constant and hence the energy densityEnergy density of the material.
