Selective de-cross-linking of transformable, double-network hydrogels: preparation, structural conversion and controlled release |
| 초록 |
Hydrogels are soft materials that have 3D cross-linked network structures and confine considerable amount of water. We prepared stimuli-responsive double-network hydrogels that are formed by sequential polymerization reactions and show chemical transformation by selective de-cross-linking without structural failure, taking advantage of chemical orthogonality. The hydrogel consist of self-immolative and thermoresponsive network that established together the double-network structure through a thiol-ene click reaction and radical polymerization. The hydrogel exhibited enhanced mechanical strength but transformed through the selective de-cross-linking by a molecular stimulus, which significantly alters physical properties of the material such as tunable toughness and lower critical solution temperature (LCST) behaviour. In addition, the material displayed a controlled, triggered release. |
