Abstract:

In this review, we focus on the design principle of stretchable and tough hydrogels as well as the applications in the fields of tissue engineering and flexible electronic devices. Through connecting hydrogel network structures, toughening mechanisms and chemical structures with macroscopic mechanical properties, we mainly discussed the research progress of single network hydrogel, double network hydrogel, nanocomposite hydrogel and so on. The summary and outlook of the new ideas and directions of stretchable and tough hydrogels were also demonstrated at last.

Key words: Tough hydrogel, Toughness enhance, Single network hydrogel, Double network hydrogel, Nanocomposite hydrogel, Tissue engineering, Flexible electronic device
