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

Abstract

Silver nanoparticle-decorated multilayered titanium carbide MXene (Ag/Ti₃C₂T_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/Ti₃C₂T_x@gelatin/PAAm is synthesized by a one-pot procedure and displays a good near-infrared light-triggered shape-memory performance.
