The Nanomedicine Research Center of the Changzhou Industrial Technology Research Institute of Zhejiang University has developed graphene anti-smog mask, which has a PM2.5 filtering efficiency of 96.4%, on.
The mask uses functional graphene non-woven filter element, which is excellent in physical dust isolation, PM2.5 and PM10 isolation and anti-bacteria performance.
It is also able to filter pollen and other kinds of dust. It can keep off smog because graphene can absorb PM2.5 and smaller particulates.
