Preparation method of tea polyphenols/chitosan nanofiber membrane

The invention relates to a preparation method of tea polyphenols/chitosan nanofiber membrane, wherein, a tea polyphenols/chitosan nanofiber membrane is made from tea polyphenols/chitosan nanofibers with the diameter of 300 to 500 nm, and the preparation process of the tea polyphenols/chitosan nanofibers comprises the following processing steps: preparing a chitosan acid solution with the mass concentration of 40 g/L to 70 g/L; preparing a tea polyphenols solution; preparing a solution for spinning; filling the solution for spinning into a syringe of an electrostatic spinning device for carrying out electrostatic spinning, and obtaining the tea polyphenols/chitosan nanofibers. The invention has the advantages that the preparation process is simple, and the prepared membrane has broad-spectrum sterilization and higher bacteriostasis effect on escherichia coli and staphylococcus aureus within 24 hours. The invention can be used in the filed of medical treatment and health, food packagingand the like.
