Embodiment 1
[0029] Example 1 Preparation of Cs / GP / Gel biomimetic cartilage composite scaffold material (Cs / GP / Gel mass ratio 1:15.2:3.7) (as a comparative example)
[0030] Weigh 2.2 g of chitosan powder, add it into 100 mL of 0.1 mol / L acetic acid solution, and stir it magnetically for 2 h at 40° C. to make it evenly mixed. Centrifuge at 1000rpm for 0.5h to degas and deslag the chitosan acetic acid solution. Weigh 20.0 g of sodium β-glycerophosphate powder, add it into 20 mL of deionized water, and stir magnetically at room temperature for 30 min to dissolve it evenly. Weigh 6.0 g of gelatin particles, add to 100 mL of deionized water, and stir magnetically for 30 min at 40°C to make them evenly mixed. At room temperature, the prepared chitosan acetic acid solution was stirred rapidly on a magnetic stirrer. During the stirring process, the β-sodium glycerophosphate solution was slowly added drop by drop, and the solution was fully stirred for 30 minutes to prepare a Cs / GP solution. Obs...
Embodiment 2
[0031] Example 2 Preparation of Cs / GP / Gel biomimetic cartilage composite scaffold material (Cs / GP / Gel mass ratio 1:6.7:1.6) (as a comparative example)
[0032] Weigh 2.5 g of chitosan powder, add it into 100 mL of 0.1 mol / L acetic acid solution, and stir magnetically for 3 h at 50° C. to make it evenly mixed. Centrifuge at 1000rpm for 0.5h to degas and deslag the chitosan acetic acid solution. Weigh 24.0 g of sodium β-glycerophosphate powder, add it to 16 mL of deionized water, and stir magnetically at room temperature for 40 min to dissolve it evenly. Weigh 7.0 g of gelatin particles, add to 100 mL of deionized water, and stir magnetically for 40 min at 50°C to mix evenly. At room temperature, the prepared chitosan acetic acid solution was stirred rapidly on a magnetic stirrer. During the stirring process, the β-sodium glycerophosphate solution was slowly added drop by drop, and the solution was fully stirred for 30 minutes to prepare a Cs / GP solution. Observe that there is...
Embodiment 3
[0033] Example 3 Preparation of Cs / GP / Gel biomimetic cartilage composite scaffold material (Cs / GP / Gel mass ratio 1:6.7:1.0) (as a comparative example)
[0034] Weigh 3.0 g of chitosan powder, add it into 100 mL of 0.1 mol / L acetic acid solution, and stir it magnetically for 4 hours at 50° C. to make it evenly mixed. Centrifuge at 1000rpm for 1h to degas and deslag the chitosan acetic acid solution. Weigh 30.0 g of sodium β-glycerophosphate powder, add it to 10 mL of deionized water, and stir magnetically at room temperature for 60 min to dissolve it evenly. Weigh 8.0 g of gelatin particles, add to 100 mL of deionized water, and mix evenly with a magnetic stirrer at 60°C for 60 min. At room temperature, the prepared chitosan acetic acid solution was stirred rapidly on a magnetic stirrer. During the stirring process, the β-sodium glycerophosphate solution was slowly added drop by drop, and the solution was fully stirred for 60 minutes to prepare a Cs / GP solution. Observe that ...
