A team of researchers from the University of Toronto’s Faculty of Applied Science & Engineering are developing a new way to coat tiny particles of copper onto the inside of fabrics, including those used in face masks – a technology that could provide an extra layer of safety against COVID-19.

The goal is to deposit very fine copper particles onto both woven and non-woven fabrics using twin-wire arc (TWA) spray technology. The fabric would then be used in one of the layers of a reusable fabric face mask. It’s anticipated the copper-embedded fabric will not affect filter or flow rate parameters and will be able to kill most viral and other pathogens within a few minutes....
