On January 11, the reporter learned at a press conference held by Changzhou 1nstitute of industrial technology of Zhejiang University that Changzhou name1 Biotechnology Co., Ltd., the incubator of the 1nstitute, has successfully developed a super strong graphene PM2.5 anti-bacterial and anti haze mask relying on the nano medicine research center of Changzhou 1nstitute of technology of Zhejiang University and the Nobel prize work station of Changzhou high tech Zone, The filtration efficiency of PM2.5 was 96.4% and the inhibition rate to Escherichia coli was 99.8%
in 2013, the international joint research group led by members of the company’s scientific research team first revealed the antibacterial molecular mechanism of graphene, leading the research and development of antibacterial functional nano materials, and won the praise of many domestic and foreign peers< According to Xue Chi, director of the scientific research management department of the Research 1nstitute, the new multifunctional protective mask developed by the company adopts the latest functional graphene non-woven fabric filter element, which has super strong physical dust isolation, PM2.5 and PM10 isolation functions, antibacterial performance, and can also filter pollen and other dust. 1ts anti haze mechanism is the adsorption of graphene on PM2.5 and below. 1n particular, the use of multi-layer graphene, can be firmly small particles "trapped.". At the same time, graphene itself has excellent antibacterial properties. 1ts antibacterial mechanism is that graphene has a strong interaction with the cell membrane of bacteria, which can cut the cell membrane of bacteria and extract a large number of phospholipid molecules from the cell membrane
