Surface Treatment of Non-woven Polypropylene Used in Personal Protective Equipment to Reduce SARS-CoV-2 Spread

Abstract

The CDC recommends healthcare personnel who work with COVID-19 patients wear personal protective equipment to protect themselves from infection. Polypropylene (PP) is commonly used to make isolation gowns and N95 masks. Recent evidence has shown that PP, provides SARS-CoV-2 viability up to 72 hours. The non-woven PP used in face masks underwent three separate treatments with the following materials: oxygen plasma, polyethylene glycol, and hyaluronic acid. The material was then evaluated for its tensile properties, breathability, cytotoxicity, and ability to adsorb SARS-CoV-2 spike protein. The masks were breathable, non-cytotoxic, and adsorbed more spike protein than controls. This indicates they are potential methods to enhance masks against COVID-19.
