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

ABSTRACT: The 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. The host-guest assembly is constructed through interactions between host and guest molecules (CD-Al₂O₃ NPs act as the host, and HEMA-Ad acts as the guest). The characterization results of the materials show that there are two kinds of supramolecular interactions, namely, the host-guest interaction and the hydrogen bonding. The material possesses good thermal stability (heat-resisting temperature can reach 200 °C) and good electrical performance. The storage modulus of the
