Example Embodiment
[0026] Example 1
[0027] Stir the pig skin collagen with 0.1mol / L acetic acid solution at 0℃ until it is completely dissolved, and prepare a 2.5mg / mL collagen solution, and then add 1% citric acid-N-hydroxysuccinyl based on the weight of animal collagen The imine ester was stirred and reacted at 0°C for 6 hours. After the bubbles were removed, it was cast into a film and dried to obtain a white transparent collagen film; firstly, tyrosinase was prepared into a solution with a concentration of 1% by weight, and then the dried collagen The membrane is immersed in the above solution and reacted at 20°C for 4 hours. After the reaction, the collagen membrane is taken out, the surface is washed with water, and dried to obtain a modified collagen membrane.
[0028] The tensile strength of the obtained collagen film was 22.401 MPa, the elongation at break was 6.57%, and the water absorption was 151.37%.
Example Embodiment
[0029] Example 2
[0030] Stir the pig skin collagen with 0.2mol / L acetic acid solution at 2℃ until it is completely dissolved, and prepare a 5mg / mL collagen solution, and then add 2% malic acid-N-hydroxysuccinimide based on the weight of animal collagen Amino ester, stirred and reacted at 2°C for 5 hours, cast into a film after removing bubbles, and dried to obtain a white transparent collagen film; firstly, tyrosinase was prepared into a solution with a concentration of 3% by weight, and then the dried collagen film Soak in the above solution and react at 25°C for 3 hours. After the reaction, the collagen membrane is taken out, the surface is washed with water, and dried to obtain a modified collagen membrane.
[0031] The tensile strength of the obtained collagen membrane was 25.652 MPa, the elongation at break was 6.12%, and the water absorption was 144.57%.
Example Embodiment
[0032] Example 3
[0033] Stir fish skin collagen with 0.5mol / L acetic acid solution at 5℃ until it is completely dissolved, and prepare 7.5mg / mL collagen solution, and then add 3% tartaric acid-N-hydroxysuccinimide based on the weight of animal collagen Urethane, stirred and reacted at 5°C for 4.5h, after removing bubbles, cast into a film, and dried to obtain a white transparent collagen film; firstly, laccase is prepared into a solution with a concentration of 5% by weight, and then the dried collagen film is soaked In the above solution, react at 30°C for 2 hours. After the reaction, the collagen membrane is taken out, the surface is washed with water, and dried to obtain a modified collagen membrane.
[0034] The tensile strength of the obtained collagen membrane was 24.02 MPa, the elongation at break was 5.71%, and the water absorption was 138.22%.
