The research team utilized accessible and affordable equipment to improve N95 masks and cut wastehave created a practical method for producing N95 face masks that are both excellent germ barriers and on-contact germ killers. The antiviral and antibacterial masks may be worn for longer periods of time, which would result in less plastic waste as the masks would not need to be replaced as often.
The researchers successfully grafted broad-spectrum antimicrobial polymers onto the polypropylene filters used in N95 face masks, according to the study that was recently published inAn N95 respirator mask is designed to provide a very tight fit on the face and highly effective airborne particle filtering.
“The process that we developed uses a really simple chemistry to create this non-leaching polymer coating that can kill viruses and bacteria by essentially breaking open their outer layer,” said Zha. “It’s very straightforward and a potentially scalable method.” Thanks to a National Science Foundation Rapid Response Research grant, Zha and Palermo started their research in 2020 when N95 face masks were in short supply.
