Abstract

The invention discloses a preparation method of an antifouling and antibacterial polypropylene non-woven fabric finished with silk fibroin for bandages. The method includes the steps that a grafting solution is dropwise added to the surface of a polypropylene non-woven fabric obtained after irradiation-plasma pretreatment; the polypropylene non-woven fabric is covered with a quartz plate, placed in an ultraviolet lamp box for irradiation, taken out, ultrasonically washed with ultrapure water and ethanol alternately, put into a polyhexamethylene guanide hydrochloride aqueous solution, taken outafter a reflux reaction, ultrasonically washed with ultrapure water and ethanol alternately, and then subjected to vacuum drying; the obtained surface-functionalized antifouling and antibacterial polypropylene non-woven fabric is dipped in a silk fibroin solution and subjected to two-dipping and two-rolling, and the dipped and rolled cloth specimen is dried, treated with an ethanol solution, dried to a constant weight and then placed in a dryer for balance; the obtained silk fibroin functionally-modified polypropylene non-woven fabric is dipped in a graphene finishing liquid, and the non-woven fabric is treated with a small padder, dried and then baked.

Description

technical field [0001] The invention belongs to the technical field of bandage products, and in particular relates to a preparation method of an antifouling and antibacterial polypropylene nonwoven fabric finished with silk fibroin for bandages. Background technique [0002] Graphene has aroused a research boom in the academic field because of its outstanding electronic conductivity, high specific surface area and mechanical properties. Graphene has carrier characteristics, high electron mobility, and stable migration speed, and the electron conduction efficiency is much greater than the movement speed of electrons in metal conductors or semiconductors. The remarkable electronic properties of graphene make it possible to achieve good electron conduction effect with a small amount. At the same time, graphene is biocompatible and has been studied and applied to biosensors. However, the application of graphene in the field of medical textiles has been rarely studied. As a na...
