Tough, Self‐Healing Hydrogels Capable of Ultrafast Shape Changing

Achieving multifunctional shape-changing hydrogels with synergistic and engineered material properties is highly desirable for their expanding applications, yet remains an ongoing challenge. The synergistic design of multiple dynamic chemistries enables new directions for the development of such materials. Herein, a molecular design strategy is proposed based on a hydrogel combining acid-ether hydrogen bonding and imine bonds. This approach...
