The self‐healable hydrogels have attracted increasing attention due to their promising potential for ensuring the durability and reliability of hydrogels. However, they still face a serious challenge to achieve a positive balance between mechanical and healing performance, especially for the room‐temperature autonomous self‐healable hydrogels. Herein, a simple but efficient strategy to fabricate a kind of dynamic boronate and hydrogen bonds dual‐crosslinked double network (DN) hydrogel based on a UV‐initiated one‐pot in situ polymerization of N‐acryloyl glycinamide (NAGA) in polyvinyl alcohol‐borax slime is reported. The obtained PN‐x/PB hydrogels, especially with high content of PNAGA, are shown to possess high mechanical strength, high toughness, and fatigue‐resistance properties as well as excellent self‐healability at room temperature (nearly 88% self‐healing efficiency based on the strain compression test), due to the dynamic DN structure, and the combination of the adaptable and reconfigurable dynamic boronate bonds and hydrogen bonds. Considering the easily available materials and simple preparation process, this novel strategy should offer not only a kind of dynamic DN hydrogel with robust mechanical performance and high self‐healing capability, but also enrich the methodological toolbox for synergistic integration of dynamic covalent bonds and hydrogen bonds to surmount the tradeoff between mechanical properties and self‐healing capacity of hydrogels.

动态共价键和氢键协同整合的一种可行策略，以克服水凝胶的力学性能和自愈能力之间的平衡

可自我修复的水凝胶由于具有确保水凝胶的耐用性和可靠性的潜在潜力而受到越来越多的关注。但是，它们仍然面临着巨大的挑战，要在机械性能和愈合性能之间取得积极的平衡，尤其是对于室温自主的自修复水凝胶而言。本文是一种简单而有效的策略，可基于N丙烯酰基甘氨酰胺（NAGA）在聚乙烯醇中的UV引发的单锅原位聚合制备一种动态的硼酸酯和氢键双交联双网络（DN）水凝胶。据报道硼砂煤泥。获得的PN‐ x/ PB水凝胶，尤其是PNAGA含量高的凝胶，具有很高的机械强度，高韧性和抗疲劳性能，并且在室温下具有出色的自修复性（基于应变压缩的自修复效率接近88％）测试），这归因于动态DN结构以及可适应和可重构的动态硼酸酯键和氢键的组合。考虑到容易获得的材料和简单的制备工艺，这种新颖的策略不仅应提供一种具有强大机械性能和高自我修复能力的动态DN水凝胶，而且应丰富用于动态共价键和氢键协同整合的方法学工具箱。克服机械性能和水凝胶自愈能力之间的权衡。
