Silver-decorated MXene nanosheets as a radical initiator for polymerization and multifunctional hydrogels.

Silver nanoparticle-decorated multilayered titanium carbide MXene (Ag/Ti 3 C 2 T x ) itself is capable of initiating the polymerization of a variety of acrylic monomers, due to it being able to generate hydroxyl radicals via the pseudo-Fenton reaction. Furthermore, double-network hydrogel Ag/Ti 3 C 2 T x @gelatin/PAAm is synthesized by a one-pot procedure and displays a good near-infrared light-triggered shape-memory performance.
