Beschreibung
Zusammenfassung:	Polymer nonwoven nanoweb containing ionic functional group and respiratory mask including the same are provided. The polymeric nonwoven web comprises polymer fibers having a diameter in the nanometer range and having a polymer with an ionic functional group in its main chain or side chain. The ionic functional group may be a sulfonate group, an ammonium group, an azanide group, a phosphonate group, a phosphate group, or a zwitterion group having two of these ionic functional groups linked. The polymeric nonwoven web may further comprise a counter ion having a charge of opposite sign to the charge of the ionic functional group, such as Ag+ or I−.
