| titleOfInvention | Preparation method of nano composite hydrogel with rapid temperature response and high mechanical property |
| abstract | The invention discloses a preparation method of nano composite hydrogel with rapid temperature response and high mechanical property. The preparation method comprises the following steps of dispersing inorganic nano particles laponite and monomer N-isopropylacrylamide (NIPAm) into water; removing oxygen and adding an initiator after evenly agitating; packaging the reaction liquid into a die to seal, and rapidly freezing for 10-40 seconds in liquid nitrogen, and then putting the reaction system at the temperature of -8 to -28 DEG C to react for 24-72 hours, so as to obtain a target product. Solvent crystal is utilized as a pore-forming agent by changing polymerization temperature; no other substances and after-treatment are needed; and the preparation process is further simplified; and the reaction is simple and controllable. The prepared hydrogel has the same rapid response and high mechanical property; the response speed and the mechanical property can be adjusted by changing the content of an inorganic cross-linking agent and the freezing reaction temperature; and the preparation method has a wide application range. |
