Abstract

The invention provides silk fibroin based antibacterial nano-fibers. The silk fibroin based antibacterial nano-fibers are prepared from the following components in parts by weight: 100 to 150 parts ofsilk fibroin, 4 to 8 parts of titanium dioxide, 20 to 30 parts of chitosan, 10 to 15 parts of nano copper oxide and 10 to 15 parts of polyethylene oxide. The invention further provides a preparationmethod of the silk fibroin based antibacterial nano-fibers; the silk fibroin based antibacterial nano-fibers, prepared by the preparation method, have good biocompatibility, anti-sticking performance,good antibacterial effect and excellent color fixing effect.

Description

technical field [0001] The invention belongs to the technical field of antibacterial fiber preparation, and in particular relates to a silk fibroin-based antibacterial nanofiber and a preparation method thereof. Background technique [0002] Nano antibacterial material is a new type of material with antibacterial properties. Due to the special effect of high specific surface area and high reactivity of the antibacterial agent in the material, the overall antibacterial effect is greatly improved, and it can make microorganisms including bacteria, fungi, yeast, Growth and reproduction of algae, viruses etc. are kept at a low level. Various products made of antibacterial materials have hygienic and self-cleaning functions, which can effectively prevent the spread of bacteria and strengthen the mechanical properties of antibacterial materials. Nano antibacterial products can not only effectively prevent people from people, people from things, things Bacterial cross-infection wi...
