Embodiment 1
[0042] This example has the composite hydrogel preparation method of double network structure and comprises the following steps:
[0043] Weigh 0.2g of polyethylene glycol methacrylate and dissolve it in 10mL of pure water to form an aqueous solution, then weigh 2g of N-isopropylacrylamide and 0.02g of graphene oxide and add them to the above solution, stir magnetically for 4 hours, and ultrasonically Mix evenly to form a uniform mixed solution, then add 0.3g of ammonium persulfate to the mixed solution, stir magnetically to form a uniform reaction mixed solution, and finally pour the reaction mixed solution into a mold and place it in a water bath at 50°C for 3 hours to react , to obtain a temperature-responsive highly elastic hydrogel.
[0044] It was found through testing that in the hydrogel prepared in this example, the polyethylene glycol methacrylate semi-interpenetrating poly-N-isopropylacrylamide hydrogel formed a double network structure.
[0045] After testing, the...
Embodiment 2
[0047] This example has the composite hydrogel preparation method of double network structure and comprises the following steps:
[0048]Weigh 0.5g of hydroxyethyl cellulose and dissolve it in 10mL of pure water to make an aqueous solution, then weigh 2g of N-isopropylacrylamide and 0.02g of graphene oxide into the above solution, stir magnetically for 4 hours, and mix evenly with ultrasonic waves A uniform mixed solution is formed, then 0.5 g of ammonium persulfate is added to the mixed solution, magnetically stirred to form a uniform reaction mixed solution, and finally the reaction mixed solution is poured into a mold and placed in a water bath at 50° C. for 3 hours to obtain Highly elastic hydrogels with temperature responsiveness.
[0049] It was found through testing that in the hydrogel prepared in this example, the hydroxyethyl cellulose semi-interpenetrating poly-N-isopropylacrylamide hydrogel formed a double network structure.
[0050] After testing, the phase trans...
Embodiment 3
[0052] This example has the composite hydrogel preparation method of double network structure and comprises the following steps:
[0053] Weigh 0.8g of hydroxyethyl cellulose and dissolve it in 10mL of pure water to make an aqueous solution, then weigh 2g of N-isopropylacrylamide and 0.05g of nanoclay into the above solution, stir magnetically for 2 hours, and mix with ultrasonic waves to form a uniform Uniform mixed solution, then add 0.25g ammonium persulfate to the mixed solution, magnetically stir to form a uniform reaction mixed solution, finally pour the reaction mixed solution into a mold, and place it in a water bath at 50°C for 3 hours to react to obtain Temperature-responsive highly elastic hydrogels.
[0054] It was found through testing that in the hydrogel prepared in this example, the hydroxyethyl cellulose semi-interpenetrating poly-N-isopropylacrylamide hydrogel formed a double network structure.
[0055] After testing, the phase transition temperature of the ...
