Fabrication strategies for hydrogels that provide tunable mechanical properties with predetermined responses to external stimuli, especially light, are highly desirable. In this study, a photoreversible supramolecular double network hydrogel system was synthesized, which show host–guest interaction between the network to form “smart” yet strong network. A programmable modulus change could be triggered by light irradiation. The photoresponsive hydrogel exhibit reversible switching from low modulus to high modulus upon light cycles. Furthermore, remote control of such matrices can provide potential insight for programmed materials with the on-demand control of mechanical property. |
