On the 7th, the reporter learned from Southeast University that, under the suggestion of Professor Sun Litao of the School of Electronic Science and Engineering, its partner Changzhou Carbon Star Technology Co., Ltd. recently sent 400,000 "graphene-based masks" to Wuhan.

This graphene-based KN95 mask was developed by Sun Litao. In 2016, after a third-party test, the removal rate of PM2.5 by this mask was as high as 97.1%. According to reports, this mask sprays the graphene composite solution on the filter screen, which can effectively remove (dry and wet) air dust and PM2.5. At present, some masks on the market use static electricity to adsorb tiny particles, but the moisture that is breathed out will cause the static electricity to disappear, and the adsorption effect will decrease significantly when worn for one hour, causing the adsorption to fail. Graphene-based masks can directly adsorb tiny particles with the advantage of graphene's large specific surface area. There is no problem of water vapor failure, and it can maintain a high efficiency adsorption rate for a long time. Its protective effect level has reached the highest stipulated by the new standard in 2016. Level: A level.

According to Sun Litao, because the virus in this pneumonia epidemic was mainly transmitted through droplets or aerogel formation in the air, similar to ordinary haze particles, the graphene-based masks have a good anti-virus function. A few years ago, when I learned that masks are urgently needed in Wuhan, Sun Litao called the cooperative manufacturers as soon as possible. Against the background of the general price increase of masks, we discussed with them that all the masks in stock were sent to Wuhan at a 30% discount on the lowest wholesale price. "To be honest, I didn't really think much at that time, it was the first reaction that we might help, and Wuhan may be the most needed. We have done many years of scientific research. If some achievements can directly serve the society, it is also our achievements. The greatest recognition. "Sun Litao said.

Sun Zhuoran, general manager of Changzhou Carbon Star Technology Co., Ltd., said that many companies had previously made requests for increased purchases of masks, but he declined them politely.
