Self‐Healing Dielectric Polymers: Self‐Healing of Electrical Damage in Polymers (Adv. Sci. 21/2020)

In article number 2002131, Qi Li, Jinliang He, and co‐workers summarize the recent progress in the design and synthesis of self‐healing dielectric polymers. The image represents a healing strategy of electrical tree degradation by preferential migration of the enclosed magnetic nanoparticles toward the electrical trees and subsequent healing of the electrical damaged region using a high localized temperature yielded from the aggregated nanoparticles under an oscillating magnetic field.
