Title:
METHOD FOR REGULATING AND CONTROLLING PORE STRUCTURE OF NANOFIBER FILM
Document Type and Number:
WIPO Patent Application WO/2023/273954
Kind Code:
A1
Abstract:
A method for regulating and controlling a pore structure of a nanofiber film. The method comprises the following steps: preparing a polymer spinning solution; adding a regulating and controlling agent to the polymer spinning solution and mixing and dispersing same to obtain a regulating and controlling solution, wherein the regulating and controlling agent comprises nano-silica, polyethylene glycol, myristic acid, isobutyltriethoxysilane, and water; and filtering the regulating and controlling solution, and then subjecting same to electrostatic spinning to obtain the nanofiber film. By means of adding the regulating and controlling agent to the polymer spinning solution and then carrying out electrostatic spinning, the pore structure of the nanofiber film can be regulated and controlled by adjusting the addition amount of the regulating and controlling agent so as to change the pore diameter and porosity of the nanofiber film.
