Problems solved by technology

However, most of the existing technologies use regenerated cellulose and other materials to blend and freeze-dry to prepare composite films. The uniformity and stability of the composite films prepared by this method are poor, and the tissue repair ability and drug adhesion need to be further improved.

Embodiment 1

[0025] Step 1: Take cod skin collagen, configure it into a collagen aqueous solution with a mass concentration of 1%, adjust the pH value of the collagen aqueous solution to 8.0, add 1% by mass alkaline protease, and perform enzymatic hydrolysis in a water bath at 50°C After 60 minutes, boil water to inactivate the enzyme for 10 minutes, cool to room temperature and centrifuge at 8000r / min for 15 minutes, take the supernatant and concentrate it to half of the original volume by rotary evaporation to obtain the cod skin collagen peptide extract;

[0026] Step 2: Weigh 20g of bamboo fiber, put it into 400g of NaOH solution with a mass fraction of 17.5%, and place it in a constant temperature water bath with a temperature of 100°C, boil for 60min, and then repeatedly clean the bamboo fiber with deionized water After reaching neutrality, place it in an oven at 70°C for 6 hours, and after drying, crush it into a coarse powder and pass it through an 80-mesh sieve to obtain bamboo pow...

Description

technical field [0001] The invention belongs to the technical field of preparation of tissue repair materials, and in particular relates to a preparation method of a cod skin collagen peptide composite regenerated fiber repair material. Background technique [0002] As a natural biopolymer, cellulose has biodegradability, biocompatibility and unique physical, chemical and mechanical properties, and has become a research hotspot in the field of new biomedical materials. However, most of the existing technologies use regenerated cellulose and other materials to blend and freeze-dry to prepare composite films. The uniformity and stability of the composite films prepared by this method are poor, and the tissue repair ability and drug adhesion need to be further improved. . Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a method for preparing a cod skin collagen peptide composite regenerated fiber repair mater...
