Title:
MAGNETOELECTRICITY-BASED FINE DUST FILTER AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2022/050571
Kind Code:
A1
Abstract:
The present invention relates to a magnetoelectricity-based fine dust filter comprising: a nanofiber web made of piezoelectric nanofibers and polarized by applying an electric field; and magnetostrictive particles dispersed inside the nanofibers. The present invention relates to a method for manufacturing a magnetoelectricity-based fine dust filter, comprising the steps of: preparing magnetostrictive particles; dissolving a piezoelectric material in a solvent to prepare a piezoelectric material solution; mixing the magnetostrictive particles with the piezoelectric material solution to disperse the magnetostrictive particles in the piezoelectric material solution; spinning the piezoelectric material solution by an electrospinning method to prepare a nanofiber web made of nanofibers having piezoelectricity; and applying an electric field to the nanofiber web to polarize the nanofiber web.
