Summary: We developed a water-retaining and separable adhesive hydrogel wound dressing composed of methacrylated silk fibroin (SFMA), tannic acid (TA), and urethane diacrylate (UDA). The hydrogel showed improved mechanical properties, good tissue adhesion, and hemostasis abilities due to the addition of TA with an abundance of catechol groups. The hydrogel was encapsulated by a hydrophobic polyurethane diacrylate (PUA) coating to maintain high water content, and could be separated upon peeling due to the adhesion energy being higher than the fracture energy.

Summary: This study proposes a strategy for developing strong and tough hydrogels by enhancing the interaction between the side groups on polymeric chains and the dispersing medium. Hydrogels are fabricated with a polyacrylamide-alginate double network in a choline chloride saturated solution. The hydrogels exhibit high transparency, toughness, fatigue resistance, self-healing, adhesion, as well as water retention, anti-freezing, and conductivity due to the strengthened hydrogen bonds within the dispersing medium. This research may inspire the development of tough and conductive gels for applications in e-skins, soft robots, and intelligent devices.
