Chemical structure design for eco-friendly dielectric polymer materials

Abstract

Environmentally friendly dielectric polymer materials that can subjectively adapt to environmental changes and self-restore mechanical and electrical insulation properties continue to emerge. These adaptive systems are expected to revolutionize the development of smart grids, power electronic systems, and other fields. We will present a new trend emerging in environmentally friendly dielectric design that utilizes reversible chemistry (both non-covalent and covalent) to control reactions originating at the most fundamental (molecular) level. Dielectrics designed with this molecular structure will be able to heal or recycle themselves on a macroscopic scale as a result of changes in the molecular structure of the material (i.e., rearrangement or reorganization of polymer components or aggregates). However, the ability to design the molecular structure and ensure the original excellent properties of the dielectric is of interest to researchers. This review will summarize the challenges and opportunities in chemical structure modification with respect to the needs of dielectric application scenarios and specific examples. Furthermore, it will guide the design and preparation of environmentally friendly dielectrics and promote the development of interdisciplinary research between high-voltage insulation technology and polymer chemistry.
