Abstract

A photo-responsive poly(rotaxane) hydrogel based on [c2] daisy chain was synthesized. The supramolecular hydrogel was robust with the compression stress of 3136 kPa at the strain of 90 %, the tensile strength of 297 kPa and the elongation at break of 694 %. At the same time, the gel film showed fast photoresponsive behavior even in dry state, showing 15^o bending angle under 2 s 365 nm UV irradiation. Besides, the hydrogel exhibited good fatigue resistance. Its recovery ratio remains higher than 80 % during multiple cyclic tensile and compression test, making it an alternative and promising platform for photo-responsive materials with emergent mechanical performances and attractive fatigue resistance.
