Water resistant enhanced wound healing film and preparation method thereof
A water resistant enhanced wound healing film includes components by mass volume concentration of: 5-10 mg/L of ultra-fine eggshell powder, 50-500 mg/L of ultramicroshell membrane powder or shell membrane soluble protein, 5-30 mg/L of lysozyme, 5-10 mg/L of chitosan, 0.05-5 mg/L of glycerin, and 0.1-5 mg/L of polymer polysaccharide. Also, a preparation method of the water resistant enhanced wound healing film is disclosed. The whole raw materials of the present invention are non-toxic and have good biocompatibility; the raw materials include eggshell, shell membrane and soluble mixed protein thereof, and lysozyme in residual egg white. In the present invention, various components of the eggshell waste are sufficiently used. The wound healing film has good water resistance, mechanical properties, antibacterial activity and protein absorption capacity, and low degradation rate. The method of the present invention has simple process, strong practicability, extremely low production cost, favorable resource recycling and low energy consumption.
