Embodiment 1
[0044] A kind of hydrophilic hydrogel, preparation method is as follows:
[0045] 1. Prepare the first solution, dissolve 10.0g PEGDA in 90.0g SDS aqueous solution at room temperature and normal pressure, and stir evenly to obtain the first solution.
[0046] 2. At room temperature and normal pressure, add 0.1 g of KPS, and dissolve by ultrasonication for 10 minutes. Then 4.0 mL of 2.5 wt.% TEMED aqueous solution was added, and stirring was continued for 10 minutes.
[0047] 3. Seal the gelling solution described in step 2, and let it stand at room temperature and normal pressure for 12 hours to react to prepare a hydrophilic hydrogel.
Embodiment 2
[0049] A temperature-sensitive hydrophilic hydrogel, the preparation method of which is as follows:
[0050] 1. Prepare the first solution, dissolve 0.3g PEGDA in 2.7g SDS aqueous solution at room temperature and normal pressure, and stir evenly to obtain the first solution.
[0051] 2. Configure the second solution, mix 9.7g OEGMA, MEO 2 MA was dissolved in 87.3 g of SDS aqueous solution and stirred evenly to obtain the second solution.
[0052] 3. At room temperature and normal pressure, mix the first solution and the second solution described in step 1 and step 2 evenly, add 0.1 g of KPS, and ultrasonically dissolve for 10 minutes. Then 4.0 mL of 2.5 wt.% TEMED aqueous solution was added, and stirring was continued for 10 minutes.
[0053] 4. Seal the gel-forming solution described in step 3, and let it stand for reaction at room temperature and normal pressure for 12 hours to prepare a temperature-sensitive hydrophilic hydrogel.
Embodiment 3
[0055] A wound dressing capable of rapidly absorbing heat, the preparation method of which is as follows:
[0056] 1. Prepare the first solution, dissolve 0.3g PEGDA in 2.7g SDS aqueous solution at room temperature and normal pressure, and stir evenly to obtain the first solution.
[0057] 2. Configure the second solution, mix 9.2g OEGMA, MEO 2 MA was dissolved in 82.8 g of SDS aqueous solution and stirred evenly to obtain the second solution.
[0058] 3. Prepare the third solution, blend and dissolve 0.5g CNT-OH and 0.5g SDS in 4.0g aqueous solution at room temperature and normal pressure, and ultrasonically disperse for 30 to 120 minutes.
[0059] 4. At room temperature and normal pressure, mix the three solutions described in the above steps, stir evenly, add KPS 0.1 g, and ultrasonically dissolve for 10 minutes. Then 4.0 mL of 2.5 wt.% TEMED aqueous solution was added, and stirring was continued for 10 minutes.
[0060] 5. Seal the gelling solution described in step 4, ...
