Title:
AEROSOL NANOFIBER FILTER MEMBRANE, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/137688
Kind Code:
A1
Abstract:
The present invention discloses an aerosol nanofiber filter membrane, and a preparation method therefor and the use thereof. The preparation method comprises the following steps: dissolving polyvinylidene fluoride and polyacrylonitrile to obtain a spinning solution, and spinning the spinning solution on a non-woven fabric by means of electrostatic spinning to form a membrane, thereby obtaining the aerosol nanofiber filter membrane. The aerosol nanofiber filter membrane of the present application has excellent moisture permeability and low-resistance filterability.
