Ultra-Tough Hydrogel via Hierarchical Energy Associative Dissipation

Abstract

An ultra-tough physical hydrogel based on hierarchical energy associative dissipation network is provided, which the field of polymeric materials. The stock solution of a hydrogen donor is prepared by dissolving the hydrogen donor in deionized water; the stock solution is mixed with a hydrogen acceptor, deionized water and a 10 wt % ammonium persulfate (APS) solution; the mixture is cured in a closed container; after reactants with specific functional groups and appropriate spatial structures are mixed, a hierarchical heterogeneous structure with a dynamic recovery capability can be spontaneously formed in polymerization reaction, and the mechanical properties of the hydrogel are kept stable through several energy associative dissipation paths.
