More Information
Summary:The present disclosure relates to an anti-droplet mask filter and an anti-droplet mask comprising the same, and more particularly, to a hydrophobic filter having ridges and an anti-droplet mask comprising the same. The present disclosure is directed to providing a mask filter with improved water repellency performance for effectively preventing the spread of acute respiratory syndrome virus infections.The super water-repellent anti-droplet nonwoven filter of the present disclosure shows superhydrophobicity with the surface contact angle of 160° or more due to the ridges that form a nanopatterned structure on the surface of hydrophobic fibers and the surface of bonding portions, thereby preventing the adsorption of droplets onto the surface of the filter. Additionally, the super water-repellent anti-droplet nonwoven filter of the present disclosure can capture ultrafine particles such as aerosols due to the nanopatterned structure on the surface of the super water-repellent anti-droplet nonwoven filter.
