N-Halamine-Based Polypropylene Melt-Blown NonwovenFabric with Superhydrophilicity and Antibacterial

Propertiesfor Face Masks

Abstract: Polypropylene melt-blown nonwoven fabric (PP MNF) masks can effectively block pathogensin the environment from entering the human body. However, the adhesion of surviving pathogensto masks poses a risk of human infection. Thus, embedding safe and efficient antibacterial materialsis the key to solving pathogen infection. In this study, stable chlorinated poly(methacrylamide-N,N0 -methylenebisacrylamide) polypropylene melt-blown nonwoven fabrics (PP-P(MAA-MBAA)-Cl MNFs)have been fabricated by a simple UV cross-link and chlorination process, and the active chlorine contentcan reach 3500 ppm. The PP-P(MAA-MBAA)-Cl MNFs show excellent hydrophilic and antibacterialproperties. The PP-P(MAA-MBAA)Cl MNFs could kill all bacteria (both Escherichia coli and Staphylococcus aureus) with only 5 min of contact. Therefore, incorporating PP-P(MAA-MBAA)-Cl MNF asa hydrophilic antimicrobial layer into a four-layer PP-based mask holds great potential for enhancingprotection and comfort.
