[real-time] Chinese experts develop graphene masks to block 96.4% PM2.5

On January 11, the reporter was informed at the press conference held by the Changzhou Institute of Industry and Technology of Zhejiang University that the institute’s incubation company—Changzhou NaMei Biotechnology Co., Ltd., relied on the Nanomedicine Research Center of Changzhou Institute of Technology and Changzhou. The Nobel Prize-winning workstation in the High-tech Zone has successfully developed a super-strong graphene PM2.5 anti-fog and anti-haze mask. The national authority inspection department has detected the PM2.5 filtration efficiency of 96.4% and the E. coli bacteria inhibition rate of 99.8%.

In 2013, the international joint research team led by members of the company's scientific research team revealed for the first time the antibacterial molecular mechanism of graphene, led the research in the field of research and development of antibacterial functional nanomaterials, and won the praise of many domestic and foreign counterparts.

Xue Chi, director of the research management department of the institute, introduced that the new multi-functional protective mask developed by the company uses the latest functionalized graphene non-woven filter element with super physical dust, PM2.5 and PM10 insulation functions, and antibacterial performance. Pollen and other dust can also be filtered. The anti-crucible mechanism is the use of graphene for the adsorption of fine particles of PM2.5 and below. In particular, multi-layered graphene is used to firmly trap tiny particles. At the same time, graphene itself has excellent antibacterial properties, its antibacterial mechanism is a strong role of the graphene and bacterial cell membrane, can cut the bacterial cell membrane, and a large number of phospholipid molecules on the cell membrane.
