Chinese researchers from AECC Beijing Institute of Aeronautical Materials (AECC BIAM) have developed a new type of face mask with graphene material on the key filter layer. The researchers have reportedly put a graphene-polypropylene material on the melt-blown fabric, which is the key filter layer of masks.
The graphene material is said to help the masks features stronger antibacterial properties, better air permeability and enhanced durability. The graphene face mask makes use of the nanoknife effect of the graphene material to destroy the cell wall of bacteria.
Compared with the melt-blown fabric used in traditional face masks, the new layer of graphene-polypropylene material has the function of one-way permeability, which makes the mask more comfortable for users.
The new mask is capable of lasting more than 48 hours, far longer than traditional models.
