Abstract : With the tremendous growth in electrical gadgets and electrification in recent years, there is an urgent need to utilise green/renewable energy and improve energy efficiency, energy conversion systems, and energy storage density. In the future, development in electrical power technologies will be aligned in the direction of higher power and frequency, wider bandwidth, faster speed, smaller form factor, higher temperature rating, lower cost, greater flexibility, and scalability. In this context, polymer nanocomposite dielectrics, also known as nanodielectrics, have garnered considerable scientific interest. Polymer nanodielectric combines the advantages of high dielectric constant nanofillers with high dielectric breakdown strength polymer matrix and offers the flexibility of engineering materials and structures to obtain desired and unique properties. This chapter discusses current developments in nanodielectric composites for energy storage applications with an emphasis on fundamental material concerns for two different types of polymer nanodielectrics: composites of polymer and ceramic and conductive nanoparticles. The role of tuneable nonlinear nanodielectrics in energy storage and harvesting is also discussed. The chapter highlights the applications, opportunities, and challenges associated with future developments in nanodielectrics.
