Past and future on nanodielectrics

Abstract

Flexible polymer-matrix nanodielectrics have recently been attracting more attention in the fields of frontier research internationally since the beginning of the 21st century. It would accelerate a technical reformation for the applications in new energies, bioscience and biomedical engineering, artificial intelligence, electronic skin, wearable electronic clothing, Internet of things, and electrical insulation. This review summarises the recent development and achievements of nanodielectrics, including space charge suppression, high energy density storage, partial discharge resistance, non-linear field grading properties, high thermal conductivity, and future applications in biomedical area. Special attention is given to two representative interface models that are the Lewis's diffusion electrical double-layer model and Tanaka's multi-core model. At last, some issues related to the technology of nanodielectrics have also been discussed.
