摘要：

We have demonstrated a novel strategy to enhance mechanical strength by designing dual-network (DN) structures. The novel self-healing hydrogel system composed of silk fibroin powder (SFP) and polyacrylamide (PAM) combines hydrogen bond supramolecular action. In addition, this system was prepared via a simple one-pot method of copolymerization. The SFP-PAM hydrogels could achieve high mechanical properties. The stress and strain at break were 0.65 MPa and 2250%, respectively. The hydrogels exhibited adhesive and self-healing properties. The fabricated multifunctional SFP-PAM hydrogel shows promise in potential applications in wound dressing and transparent artificial skins for body-adhered signal detection. (C) 2019 Elsevier B.V.
