Can COVID-19 bring a bio-graphene mask?

Of course. It has extremely high potential application value in the daily protection during the epidemic in COVID-19. At present, the masks made of related laser-induced graphene materials have been mass-produced, so it is possible. Graphene is a material extracted from graphite, which was originally separated from graphite. It is a highly conductive form of elemental carbon, which consists of a single flat carbon atom sheet arranged in a repeated hexagonal lattice.
