Abstract

The invention relates to a photodynamic antibacterial cellulose material and a preparation method thereof. Epsilon-polylysine is attached to the cellulose material and further modified with photo-sensitizers through amidogen of the epsilon-polylysine, the epsilon-polylysine provides a first antibacterial performance of the material, and the photo-sensitizers provide a second antibacterial performance of the material. The preparation method of the material is simple in process, mild in reaction condition and suitable for industrial production, and final cellulose products with double antibacterial performances can be used for preparing medical antibacterial fibers or daily antibacterial textiles.

Description

technical field

[0001] The present invention relates to a cellulose material that can be used for photodynamic antibacterial and its preparation method, in particular to modifying the surface of cellulose material through two processes of non-covalent electrostatic adsorption and covalent connection, loading an antibacterial photosensitizer, and thereby The formed cellulose material with high-efficiency photodynamic antibacterial properties belongs to the technical category of functional materials. Background technique

[0002] Antibacterial fiber is a functional fiber formed by introducing substances capable of inhibiting bacterial growth, that is, antibacterial agents, into the surface and interior of fibers by physical or chemical methods. With the improvement of people's living standards and the enhancement of health awareness, especially in recent years, various drug-resistant bacteria and epidemic viruses have ravaged the market, and the demand for antibacterial fibers...
