In the fight against COVID-19, scientists have successfully developed graphene face masks. These graphene face masks have an anti-bacterial efficiency around 80 percent which can also enhance to 100 percent when came in contact with sunlight for around 10 minutes. A study of the City University of Hong Kong said initial tests also showed the auspicious result in the deactivation of two species of coronavirus.

According to the researchers, graphene masks are developed at a low cost and they are non-biodegradable. Commonly used surgical masks are not anti-bacterial and it may cause risk of secondary transmission of bacterial infection when people came in contact.

Graphene masks are better than melt-blown fabric masks and activated carbon masks.

Graphene masks are special and known for their substances. Melt blown fabrics masks have activated carbon masks that have only 9 percent antibacterial efficiency and graphene masks have 80 percent antibacterial efficiency that helps the coronavirus to stay away from us.

How 10 minutes of sunlight increased the effectiveness of masks by 99%?

According to the study, high temperatures will fail the effect of coronavirus. So the team of scientists carried the research of graphene photothermal effect, so the research proves that sunlight will enhance the antibacterial effect to 99.998 percent within 10 minutes of sunlight.
The team is working in laboratories in mainland China for getting graphene material with two species of human coronavirus. The mission is to develop an anti-bacterial and reusable face mask.
