making it extra sustainable than standard disposable masks, however simply as simple to breathe in.
‘Nanotech-Based Reusable Mask is much better than the surgical or N95 masks, as it can be washed and reused. The nanoparticles are bonded to the fibers within the mask, so there is no contact with human skin when the mask is worn.’
The nanotech masks is made with two key elements: an antimicrobial coating created from copper nanoparticles and coated on a non-woven material masks which has a novel static-electricity property that pulls and traps all nanoparticles and germs.
Each are the 2 most desired properties wanted to battle Covid-19, right into a single filter, stated Professor Lam Yeng Ming, Chair of NTU’s Faculty of Supplies Science and Engineering.
“In experiments, our copper nanoparticle coating has an extremely fast and sustained antibacterial activity, with a killing efficiency of up to 99.9 percent when it meets multidrug resistant bacteria. This coating will help to reduce the spread of bacteria as it kills microbes in droplets trapped by the mask fibers, which provide excellent filtration efficiency. This should give users a double layer of protection compared to conventional surgical masks,” Lam stated
In experiments, the masks was in a position to appeal to and lure a broad vary of particulate matter: from PM10 (common particle measurement of 10 microns) to PM0.3 (0.3 microns – about 0.3 p.c or the diameter of a human hair) with a filtration effectivity of 99.9 p.c.
The nanoparticles are additionally bonded to the fibers throughout the masks, so there isn’t a contact with human pores and skin when the masks is worn.
“With our new composite filter, we can achieve up to 99.9 per cent BFE (Bacterial Filtration Efficiency), trapping almost all microbes and particulate matter from smoke or haze. Its filtration efficiency surpasses a N95 mask but allows the wearer to breathe much easier,” stated Liu Zheng, Affiliate Professor on the varsity.
