A robust double-network (DN) hydrogel fabricated by a one-pot, one-step reaction is reported. The DN hydrogels not only have high mechanical strength and extremely low underwater oil adhesion, but also exhibit excellent characteristics, such as short processing duration, moderate swelling and free shaping. The DN hydrogel is durable in artificial sea water, and its mechanical property can be easily adjusted by adjusting the crosslinking agent concentration. In addition, because a large number of free hydroxyl groups remain in their networks, the mechanical property of the hydrogel can be enhanced and repaired by presenting more glutaraldehyde in the system.
报道了一种通过一锅一步反应制备的坚固双网络（DN）水凝胶。该DN水凝胶不仅具有高机械强度和极低的水下油粘附性，还展现出诸如加工时间短、适度溶胀和可自由成型等优异特性。该DN水凝胶在人工海水中耐用，其机械性能可通过调节交联剂浓度轻松调节。此外，由于其网络中保留了大量游离羟基，通过在体系中引入更多戊二醛可增强和修复水凝胶的机械性能。
