以两亲性三嵌段共聚物为基础，合成了一系列物理性双网络水凝胶。该凝胶具有较强的疏水结构域和牺牲的氢键动力学键，具有一定的刚性和坚韧，在浓盐水溶液中甚至会变硬。此外，由于其超分子结构，该凝胶具有改善的自愈合和自恢复能力。
A series of physical double-network hydrogels is synthesized based on an amphiphilic triblock copolymer. The gel, which contains strong hydrophobic domains and sacrificial dynamic bonds of hydrogen bonds, is stiff and tough, and even stiffens in concentrated saline solution. Furthermore, due to its supramolecular structure, the gel features improved self-healing and self-recovery abilities.
