Preparation method of NIPAM-based intelligent composite hydrogel

The invention discloses a preparation method of NIPAM-based intelligent composite hydrogel. The NIPAM-based intelligent composite hydrogel is prepared by using NIPAM as the polymerization monomer, BISas the chemical crosslinking agent, potassium persulfate as the initiator, TEMED as the accelerant at 20 DEG C, GO nanosheets as the additive and ZrO2 as the enhancer to perform polymerization reaction according a certain proportion. The intelligent composite hydrogel has the advantages that the hydrogel is good in tensile property, and the problem that traditional hydrogel is poor in mechanicalstrength is solved; the hydrogel is good in temperature-sensitive performance, the volume of the hydrogel constantly degreases along with the rising of temperature, the volume suddenly changes at 30-35 DEG C and is gradually stabilized finally, and the hydrogel can have evident volume shrinkage under the irradiation of laser (500mW) of 808 nanometers and shows a good near infrared response characteristic. 本发明公开了一种NIPAM基智能复
