Can PENG, Yu-jie LIU. Synthesis of Self-healing Hydrogel and Application in Pharmaceutical[J]. Polymer Bulletin, 2021,34(3):6-12. DOI: 10.14028/j.cnki.1003-3726.2021.03.002.
Self-healing hydrogels achieve crack closure by reconnecting broken links in the hydrogel matrix. Self-healing hydrogels could restore their original structure and function after physical injury. It has multiple characteristics
such as injectability
conductivity
adhesion. In recent years
more and more attention has been paid. Self-healing hydrogels have been widely used in pharmaceutical engineering
biomedical and other fields. However
the compatibility of its toughness and rapid healing remains to be solved. Its application in the human environment remains to be further studied. In this paper
an innovative synthesis method of hydrogels with rapid self-healing ability and mechanical toughness in recent years is introduced. And its wide application in medicine. It is believed that self-healing hydrogels have long-term development prospects and considerable possibilities in the future.
