In this study, we created stimuli-responsive, dual-cross-linked hydrogels that show transformation via selective triggered head-to-tail depolymerization. The hydrogels were established based on aA primary covalent structure containing pendant functional moieties that induce non-covalent interaction with the macro-cross-linker capable of head-to-tail depolymerization. Thus, the incorporation of the macro-cross-linker reinforced the entire structure through physical cross-linking, but, at the same time, the resultant network showed rapid, selective de-cross-linking via the depolymerization reaction, which wholly reverses the chemical structure of material without structural collapse. Furthermore, we used the proposed strategy to design actuating materials that exhibit reversible, programmed, large-scale behavior, and finally demonstrated re-cross-linking by the addition of an extra macro-cross-linker after the de-cross-linking reaction.
