Effect of different healing temperature on self-healing hydrogel

A muscle mimetic polyelectrolyte–nanoclay organic–inorganic hybrid hydrogel: its self-healing, shape-memory and actuation properties

“…Self-healable hydrogels can be prepared by using different physical and chemical interactions. Physically interacting selfhealable hydrogels involve hydrogen bonding, 5,6 metal coordination, 7 hydrophobic interactions, 8 host-guest interactions, 9 p-p stacking, 10 electrostatic interactions, 11,12 Schiff base reactions, 13,14 thiol-yne click reactions 15 etc., whereas chemically interacting self-healable gels utilize light, 16 temperature 17 etc. to self-heal via the formation of new chemical bonds.…”
