A novel self-healing power cable insulating material based on host–guest interactions

Abstract

aThe insulating materials used in power cables are susceptible to damage and cracks during installation and operation. To solve this problem, we have prepared a self-healing material PVP/p(HEMA-co-BA), which is synthesized by radical polymerization using HEMA, BA, PVP and a host-guest assembly. and good electrical performance. The storage modulus of the material can be increased up to 432 MPa using a cross-linking agent at 20 C. Furthermore, the material exhibits self-healing property, and it can self-heal several times; its self-healing efficiency is relative to the dosage of the cross-linking agent.
