Self-healing versatile polyurethane (PU) hydrogel is a class of appealing material, which is by reason of its broadening application prospects such as in tissue engineering, drug delivery, and sense technol. fields. However, it is still a huge challenge to combine superior mech. robustness, thermo-responsiveness, biodegradability with self-healing capability for PU hydrogels. Herein, we fabricated a novel multifunctional PU hydrogel with fast self-healing and excellent mech. performance, largely depending on a microdomain-closed design because of the dynamic disulfide bonds embedded in hard segments as well as principally being closed in viscoelastic hard segments microdomain. Besides, PCL in soft segments provided good biodegradability, the mech. performance, self-healing capability, and biodegradability of PU hydrogels could be modulated by altering the chain extender 4-aminophenyl disulfide APDS addition amount The obtained optimal PU hydrogels showed sensitive thermo-responsiveness, rapid mech. recovery (10 min), high mech. strength (tensile stress of 3.3 MPa), superior stretching toughness (strain of 1055%), and outstanding self-healing ability (self-healing efficiency of 97%). The strategy described here provides a promising avenue to design and fabricate intelligent and multifunctional PU hydrogels.
