Abstract

The invention provides a self-repairing material based on bipyridine metal coordination and a preparation method thereof. The self-repairing material adopts 2,2' -bipyridine methyl- 4,4' -dicarboxylate as a raw material, and the self-repairing material is obtained through hydrolysis reaction, polymerization reaction and coordination. According to the preparation method of the self-repairing material based on bipyridine metal coordination, the coordination effect of metal ions is utilized, it is guaranteed that after the material is broken, reconnection can be conducted under the condition that the proper temperature and humidity are met, and self-repairing at the high temperature can be achieved.

Description

technical field

[0001] The invention belongs to the field of self-repairing materials, and in particular relates to a self-repairing material based on bipyridine metal coordination and a preparation method thereof. Background technique

[0002] Inspired by the self-healing phenomenon of living organisms, self-healing materials have emerged. Among them, after the polymer material is damaged by mechanical force, the macromolecular chain generally undergoes homogeneous or heterogeneous cracking, which makes the material produce micro-cracks that are difficult to detect. With the accumulation of time, larger cracks are generated, and the material will quickly fail. Therefore, Rapid repair of microcracks is very important for many polymer materials used in important fields. In the past ten years, various research papers on self-healing polymers have sprung up, and their applications in sensors and electronic skin have attracted widespread attention.
