Beschreibung
Zusammenfassung:	The invention provides a preparation method of a nano composite biological material, which comprises the following steps: purifying HNTs, adding water to obtain an HNTs aqueous solution, adding sodium metaphosphate into the HNTs aqueous solution to obtain HNTs with dispersed sodium hexametaphosphate, dissolving fish skin collagen into a mixed solution of a formic acid solution with the mass fraction of 98% and absolute ethyl alcohol, then adding the HNTs with dispersed sodium hexametaphosphate, and stirring uniformly to obtain the nano composite biological material. The preparation method comprises the following steps: adding a nano-composite biofilm material into a reaction kettle, carrying out magnetic stirring at room temperature, putting into an EP tube, carrying out ultrasonic oscillation for 25 minutes, carrying out electrostatic spinning to obtain the nano-composite biofilm material, carrying out freeze drying in a vacuum freeze-drying machine at-50 DEG C, and carrying out irradiation sterilization by
