Research Progress and Application of Self-Healing Hydrogels
In this paper,recent studies on self repairing hydrogels based on dynamic covalent and non covalent bonding mechanisms are reviewed.This paper mainly introduces the research situation of self-healing composite hydrogels of hydro-gen bonding,electrostatic interaction,host guest interaction,hydrophilic hydrophobic interaction,borate ester bond reac-tion,acylhydrazone bond reaction,and analyzes the limitations of various mechanisms.Finally,the research of self-heal-ing composite hydrogels is summarized and prospected.
