Nanofiber filter membrane with antibacterial and antifouling functions and preparation method thereof

Abstract

The invention provides a nanofiber filter membrane with antibacterial and antifouling functions and a preparation method thereof. The nanofiber filter membrane with antibacterial and antifouling functions is composed of a nonwoven support layer and a modified nanofiber filter layer loaded on the surface of the nonwoven support layer; the modified nanofiber filter layer is made of grafted Composition of modified nanofibers. The invention realizes the modification treatment of the nanofiber filter membrane through the grafting reaction of the nanofiber and the amphoteric compound of the grafted monomer, which integrates excellent filtration performance, sterilization performance, antibacterial performance and antifouling performance, and is a kind of A filter membrane with excellent comprehensive performance in the field of liquid filtration and separation. The preparation method is simple and controllable in process, low in cost, and has the value of large-scale promotion.

Description

Nanofiber filter membrane with antibacterial and antifouling functions and preparation method thereof technical field The present invention relates to filter membrane material preparation technical field, relate in particular to a kind of nanometer with antibacterial and antifouling function Fiber filtration membrane and preparation method thereof. Background technique Nanofiber has the advantages of large specific surface area, good biocompatibility, small fluid resistance, etc. It is widely used in the field of liquid filtration and separation, such as portable Water purification equipment, wastewater treatment equipment, reverse osmosis pretreatment, sewage separation, pharmaceutical, food, biological and drinking water industries, etc. noodle. However, the existing nanofiber filtration membrane has the defect of single function, and does not possess the properties of antibacterial and sterilization at the same time. It can be used, and it is extremely prone t...
