Development of Functional Filter Materials for Virus Protective Face Masks (Adv. Mater. Technol. 17/2023)

Virus Protective Masks In article 2300141, Uwe Rösler, Rainer Haag, and co-workers demonstrate that virus protective coating of masks filter textile is a suitable technique to minimize secondary transmission of virus in the pandemics. In this concept, nonwoven polyamide 6 (PA6) filter materials are functionalized with negatively charged linear polyglycerol sulfate (LPGS) as a virus binding functional group. LPGS coated nanofibers display efficient virus removal behavior in compare with uncoated PA6 nanofibers.
