Southern University of Science and Technology donated 600,000 anti-fog alcohol wipes and 20,000 bottles of anti-fog alcohol spray to Hubei Province. The anti-fog material was independently developed by teachers and students of Southern University of Science and Technology, which can reduce the discomfort of wearing goggles for a long time. In order to fight the epidemic and save materials in a race against time, front-line medical staff often can not replace protective equipment for a long time, goggles covered with fog, affecting the treatment of patients.
The existing goggles anti-fog method is less durable and does not guarantee the anti-fog effect of the goggles worn by medical staff for a longer period of time, and some anti-fog reagents may have problems of irritating and no second disinfection after application.
On February 26, the handover ceremony of donations of anti-epidemic materials from Southern University of Science and Technology was held on the campus of the University of Southern Science and Technology. Nanke University
Knowing this situation, Sun Dazhao, associate professor of materials science and engineering department of the University of Southern Science and Technology, and Zhang Zhili, the first undergraduate graduate of The University of Southern Science and Technology, co-sponsored the creation of Shenzhen Nanke New Materials Technology Co., Ltd., as well as the Sun Dazhao group student entrepreneurship team to make an urgent attack, on the basis of previous research to improve the development of anti-fog disinfection wet wipes suitable for goggles.
The relevant departments of the University of Southern Science and Technology coordinated the school, during the outbreak prevention and control period, for the company’s researchers to use the relevant laboratories and related equipment, coordination of raw materials, promote the rapid development and quantification of anti-fog wet wipes.

According to the introduction, with the University of Southern Science and Technology teachers and students independently developed wet wipe wipe, can form a long-lasting transparent hydrophilic protective film on the surface such as lenses. This protective film reduces the surface tension of the water droplets, so that the small water droplets form a water film, greatly reducing the possibility of light scattering, thus eliminating fog. Wipe can ensure at least 24 hours of anti-fog effect, effectively ensure the long-term work efficiency of health care workers, reduce the degree of long-term wearing goggles discomfort.
At the same time, Sun Dazhao team in wet wipes using 75% alcohol as a solvent component, the independent research and development of high-efficiency anti-fog formula ingredients reasonably dispersed in it, the organic structure of bacterial viruses has a strong destructive effect, so that it can effectively inactivate viruses, bacteria and so on. At present, the product has passed the SGS safety test, proved non-toxic, non-irritating.
“The current outbreak, the first-line medical staff encountered inconvenience and difficulties make people worried, we Nanke adults to be brave to innovate, the pursuit of excellence, to use scientific and technological strength to combat the epidemic, so that scientific and technological achievements to serve the community.” Sun said.
At the donation ceremony, Chen XI, president of the University of Southern Science and Technology, said that in this “war epidemic” without smoke, the University of Southern Science and Technology will give full play to the talents and scientific research advantages of the new era research universities and actively contribute to their own strength. “This donation is only the beginning, the next step will be the University of Southern Science and Technology will continue to step up scientific research, more independent research and development of scientific and technological achievements to the first line of epidemic prevention. “
