“…In addition to the above-mentioned factors, Yang et al have also proposed other challenges in designing self-healing dielectric polymers [201] . Elimination of chemical degradation products and competence in healing after a long waiting time (time period between damage and applying the conditions required for healing) are ideal features for self-healing insulating polymers.…”

“…Microencapsulation self-healing methods can be further divided into different categories according to the form of healing agents (monomers) and catalysts or initiators [217] . Although capsulecatalyst systems and multi-capsule systems perform well in healing mechanical damage, they are not so favourable when dealing with electrical trees in much smaller sizes, since the possibility of electrical trees contacting catalysts or all types of microcapsules will be much lower than in the case of mechanical damage [201] . Additionally, this issue cannot be resolved by raising the content of microcapsules or catalysts.…”

Smart dielectric materials with bioinspired and autonomous functions are expected to be designed and fabricated for next-generation electrical insulation. Similar to organisms, such dielectrics with self-adaptive, self-reporting, and self-healing capabilities can be employed to avoid, diagnose, and repair electrical damage to prevent catastrophic failure and even a blackout. Compared with traditional dielectrics, the utilization of smart materials not only increases the stability and durability of power apparatus but also reduces the costs of production and manufacturing. In this review, researches on self-adaptive, self-reporting, and self-healing dielectrics in the field of electrical insulation, and illuminating studies on smart polymers with autonomous functions in other fields are both introduced. The principles, methods, mechanisms, applications, and challenges of these materials are also briefly presented.
