First of all, we will provide a brief background on the self-healing hydrogels we produced which are suitable for the complex environment of nature. In this paper, disulfide bonds and acylhydrazone bonds can be combined in SH-WPU and hydrogen bonds existed in PAMAM. And the hydrogel can achieve self-healing under acid, alkaline, neutral or light environment.Self-healing for 1 h, 24 h and 48 h, the self-healing efficiency is 31.58%, 49.84% and 87.35% respectively. This effect achieved the desired effect and the repair effect is more obvious than previous research results. The hydrogels have potential applications in the field of biomaterials.

基于可逆共价键和可逆非共价键的互穿网络水凝胶的合成和自愈性能研究

首先，我们将简要介绍我们生产的适用于自然环境的自修复水凝胶。本文将SH-WPU中的二硫键和酰基hydr键结合起来，而PAMAM中存在氢键。水凝胶可在酸性，碱性，中性或轻度环境下实现自愈。自愈1 h，24 h和48 h，自愈效率分别为31.58％，49.84％和87.35％。该效果达到了预期的效果，修复效果比以往的研究结果更加明显。水凝胶在生物材料领域具有潜在的应用。
