Abstract

Self-healing hydrogels are widely used in medical fields because of their excellent properties such as self-repairing properties of damage and fatigue, and good biocompatibility. In this review, the repair mechanism of self-repairing hydrogels is introduced from two aspects: dynamic reversible covalent bonds and non-covalent interactions, at the same time, the research progress of self-repairing natural polymer hydrogels with collagen, cellulose, chitosan and hyaluronic acid, as well as self-repairing hydrogels with temperature, pH and photosensitive self-healing hydrogels are introduced.
