Abstract

Electromagnetic wave absorption coatings can effectively minimize electromagnetic radiation and are widely used in the military and civil field. However, even small scratches on the coating can lead to a large decline of absorption ability and bring serious consequences. To enhance the lifetime of electromagnetic wave absorbing coating, a kind of self-healing electromagnetic wave absorbing coating is developed by introducing host-guest interactions between the absorbing fillers and polymer matrix. After being damaged, the cracks on this coating can be healed completely with the aid of small amounts of water. Simultaneously, the electromagnetic absorbing ability of the coating is restored along with the self-healing process.

摘要

电磁波吸收涂层可以有效地减少电磁辐射，因此被广泛应用于军事和民用领域。然而，涂层上哪怕非常小的刮痕也会导致其吸波能力大幅下降，从而带来严重的后果。为了提高电磁波吸收涂层的使用寿命，通过在吸收剂和聚合物基体之间引入主客体相互作用，开发出了一种自修复电磁波吸收涂层。这种涂层在受到损坏后，只需加入少量的水，就能借助自修复过程实现完全愈合，同时涂层的吸波能力也能得到恢复。
