A robust hydrogel with a reliable deformation region in an aqueous environment is proposed. The gel has a homogeneous network where hydrophilic/hydrophobic components are uniformly distributed. In an aqueous environment, aggregated hydrophobic segments serve as "mechanical fuse links," inhibiting sudden macroscopic fracture. The gel endures threefold stretching for more than 100 cycles in water without mechanical hysteresis.
提出了一种在水介质中具有可靠变形区域的强韧水凝胶。该水凝胶具有均匀分布亲/疏水组分的均匀网络。在水介质中，聚集的疏水链段充当“机械熔丝键”，抑制突然的宏观断裂。该水凝胶在水中经受三倍拉伸超过 100 个循环而无力学滞后。
