摘要： Silk hydrogels are promising biomaterials, however, owing to their homogeneous unordered structure, regenerated silk fibroin hydrogels (rSF) have unsatisfactory mechanical properties. In this study, inspired by the "brick and mortar" layered structure of natural nacre, we use SF solutions as an organic "mortar" to coat silk fabrics with an ordered network structure to prepare a multilayered SF@FC* (silk fibroin solution coated onto fabrics and then hot-pressed) hydrogel by layer-by-layer assembly. Additionally, carbon nanomaterials are deposited as inorganic "bricks" on the silk fabric's surface to further enhance the mechanical properties. These building blocks are stacked, hot-pressed, and further crosslinked between the layers to densify the multilayered SF@FC*composite hydrogels, whose tensile strength and toughness are 18.7 MPa and 40.3 MJ m-3, respectively. Furthermore, the materials exhibit sufficient fracture energy, fatigue resistance, and good biocompatibility. The multilayered SF@FC* hydrogels with remarkable mechanical properties provide insights into the design of structural materials and potential applications of high-performance materials in aerospace, biomedicine, and electronics.
