Title:
ELECTROSTATIC SPINNING MICRO-NANO FIBER MATERIAL FOR AIR FILTRATION
Document Type and Number:
WIPO Patent Application WO/2020/000619
Kind Code:
A1
Abstract:
An electrostatic spinning micro-nano fiber material for air filtration. The micro-nano fiber material is prepared by means of the following method: growing a PEI/titanium dioxide fiber layer on a receiving substrate; growing a PSU/silicon dioxide fiber layer on the PEI/titanium dioxide fiber layer; and peeling off the fiber layers from the receiving substrate. A PEI/titanium dioxide fiber layer spinning solution is prepared, and the PEI/titanium dioxide fiber layer is grown on the receiving substrate by means of electrostatic spinning. A PSU/silicon dioxide fiber layer spinning solution is prepared, and the PSU/silicon dioxide fiber layer is grown on the PEI/titanium dioxide fiber layer by means of electrostatic spinning. Since the filtering material uses a more advanced structure and employs more advanced components and an optimized process, the filtering efficiency is higher than that of a conventional filtering material, the clogging capacity is greatly increased, and the air permeability can also be properly balanced.
