Abstract
The present invention provides a protective mask with an ultrafine fibrous coating. The ultrafine fibrous coating includes partially gelled submicron fibers interweaved with nanofibers and a biocide encapsulated in, surface-attached onto, blended with, physically trapped, and/or chemically linked to the submicron fibers and nanofibers. In an example, a microfibrous substrate with the coating assembles with other microfibrous substrates to form a protective mask having N95 level of protection and bacteria-killing capability.
