摘　　要：Background and Originality Content Hydrogels,which retain a large amount of water,possess tunable porous three-dimensional nanostructure.They are known to resemble human tissue that can offer many advantages in biomedical applications such as tissue engineering,drug delivery and surgical dressings.1141 Stimuli-responsive hydrogels,referred as smart hydrogels can rapidly respond in a controlled manner to external stimuli,such as temperature,pH,light,etc.[s]In particular,the thermal-responsive hydrogels exhibit sol-to-gel phase transi­tion upon heating up to lower critical gelation temperatures(CGTs).
