Description

technical field [0001] The invention relates to the technical field of membrane materials, in particular to an antibacterial and water-resistant polyvinyl alcohol nanofiber membrane. Background technique [0002] Polyvinyl alcohol is well known because it is non-toxic, harmless and degradable, making it almost pollution-free to the environment. In addition, it has unique oil resistance, abrasion resistance, solvent resistance, and film-forming properties, etc. With excellent performance, it is one of the commonly used materials for nanofiber membranes. Although the polyvinyl alcohol material is simple to process, environmentally friendly and has excellent performance, the water resistance of the polyvinyl alcohol nanofiber membrane is poor. It is not very ideal, which limits the application of polyvinyl alcohol nanofiber membranes. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes an a...
