Document Type and Number:
WIPO Patent Application WO/2019/184099
Kind Code:
A1
Abstract:
Nanomaterials (100) in particular HEPA air filter media. One embodiment is a nanomaterial (100) that includes a plurality of nanofibers (140) that form a randomly interwoven network defining three-dimensional pores (160) therein. The nanomaterial further includes a plurality of beads (120) with a bead diameter of 2-20 μm that are distributed randomly within the plurality of nanofibers (140). The beads (120) support the nanofibers (140) to prevent the pores (160) from collapsing.
