Hydrogel is a three-dimensional network structure material with high water absorption and water retention.It has received extensive attention due to its unique physical and chemical properties and wide application prospects.There are many methods for the synthesis of hydrogels,including chemical crosslinking,physical crosslinking,self-assembly,etc.The properties of hydrogels obtained by different preparation methods are also different,such as mechanical properties,water absorption properties,biocompatibility,etc.In the biomedical field,hydrogels are used as drug carriers,tissue engineering scaffolds,wound dressings,etc.Although significant progress has been made in the research of hydrogels,there are still some challenges,such as improving the mechanical strength of hydrogels and reducing costs.In this paper,the research status of hydrogels is reviewed in order to provide new ideas for its development and application.
