Abstract

Dielectric polymer materials with high-density energy storage are ubiquitous in power electronics used in hybrid electric vehicles and electrical weapons. The continuous miniaturization and increased functionality of modern electronic devices demands improvement in energy storage as well as thermal management, as the heat generated by circuitry increases exponentially with miniaturization and functionality. In this chapter, we explore the mechanisms for thermal conduction in polymeric materials, and review the recent progress in the processes and thermal management of dielectric polymers. Particular attention is paid to the strategies towards improving both their thermal conductivity and energy storage density in polymer nanocomposites. The future opportunities and challenges for polymer materials having improved dielectric energy storage, highly thermal conduction, and functionality are also addressed.
