Competitive relationship between electrical degradation and healing in self‐healing dielectric polymers

The concept of self-healing dielectric polymers has been heatedly discussed, with the expectation high damage resistance and longer service time. However, there is still a lack analysis on competitive relationship between electrical degradation self-healing. authors discussed this in two stages: design strategies operation polymers. Since requirements for excellent insulating or mechanical properties are not consistent demands capability, trade-offs necessary during polymeric systems. In stage polymers, some key factors that affect lifetime non-autonomous analysed, including efficiency repeatability self-healing, frequency healing maintenance. For autonomous dielectrics, simultaneous processes ageing investigated using epoxy resin based microcapsules situ-generated radicals. A quicker recovery properties, terms partial discharge magnitude, was observed under appropriate voltages. ability might vanish when voltage too high, verifying
