This Coating Makes Viruses Slide Right Off Fabric: PPE Would Last Much Longer If...

Description:
Many of the 'blue masks' are sprayed in something called 'PFTE', polytetrafluoroethylene (PTFE, the same polymer that makes Teflon nonstick. Breathing this in is extremely harmful to human health. It breaks down on a flexible substrate, and with temperature variances. It can cause the 'symptoms' of 'covid-19'. ------------- Masks and gowns are crucial to protect health workers from the spread of viruses, but they only do so much. Germs can still latch onto the material that protective equipment is made of, and diseases can spread when people touch those off those masks or touch their gowns. What if, like water sliding off a raincoat, viruses could be repelled by the textiles used for PPE, clothing, and even the seats in a hospital waiting room? University of Pittsburgh researchers have created a washable textile coating that repels liquids, such as blood and saliva, and also prevents viruses from adhering to its surface. Their work, which was recently published in the journal ACS Applied Materials and Interfaces, began before the COVID-19 pandemic, but the researchers see it being especially relevant now. Not only could this coating potentially improve how protective PPE is, says Paul Leu, coauthor of the research, associate professor of industrial engineering at Pitt, and head of the school’s Laboratory for Advanced Materials—it could also help address critical PPE shortages, such as what hospitals across the world are currently facing. “One of the main ...
