Hydrogel materials show promise for diverse applications, particular as biocompatible materials due to their high water content. Despite advances in hydrogel technology in recent years, their application is often severely limited by inadequate mechanical properties and time-consuming fabrication processes. Here we report a rapid hydrogel preparation strategy that achieves the simultaneous photo-crosslinking and establishment of biomimetic soft–hard material interface microstructures. These biomimetic interfacial-bonding nanocomposite hydrogels are prepared within seconds and feature clearly separated phases but have a strongly bonded interface. Due to effective interphase load transfer, biomimetic interfacial-bonding nanocomposite gels achieve an ultrahigh toughness (138 MJ m⁻³) and exceptional tensile strength (15.31 MPa) while maintaining a structural stability that rivals or surpasses that of commonly used elastomer (non-hydrated) materials. Biomimetic interfacial-bonding nanocomposite gels can be fabricated into arbitrarily complex structures via three-dimensional printing with micrometre-level precision. Overall, this work presents a generalizable preparation strategy for hydrogel materials and acrylic elastomers that will foster potential advances in soft materials.

水凝胶材料显示出多种应用的前景，特别是由于其高含水量而作为生物相容性材料。尽管近年来水凝胶技术取得了进步，但其应用往往受到机械性能不足和耗时的制造工艺的严重限制。在这里，我们报告了一种快速水凝胶制备策略，该策略实现了同时光交联和仿生软硬材料界面微结构的建立。这些仿生界面结合纳米复合水凝胶可在几秒钟内制备出来，具有清晰分离的相，但具有牢固的结合界面。由于有效的相间负载转移，仿生界面粘合纳米复合材料凝胶实现了超高韧性（138 MJ m ^-3）和卓越的拉伸强度（15.31 MPa），同时保持了与常用弹性体（非水合弹性体）相媲美或超过的结构稳定性。 ） 材料。仿生界面粘合纳米复合凝胶可以通过微米级精度的三维打印制造成任意复杂的结构。总体而言，这项工作提出了水凝胶材料和丙烯酸弹性体的通用制备策略，这将促进软材料的潜在进步。
