600,000 pieces of goggles anti-fog wipes developed by SUSTC have arrived
The newspaper (Reporter Kuang Xiaoying) front-line medical staff wear masks and goggles for a long time, and the goggles are full of fog, which affects work efficiency and is uncomfortable. Recently, Sun Dazhen, an associate professor at Southern University of Science and Technology, independently developed a new anti-fog material-anti-fog disinfection wipes and anti-fog alcohol spray. The anti-fog effect of the goggles wiped with a wet towel can last for 24 hours. The first batch of products had a good effect after trials. The team quickly expanded its production capacity and produced 600,000 anti-fog alcohol wipes and 20,000 bottles of anti-fog alcohol sprays within 5 days, fully supporting Wuhan.
On February 26, after a brief donation ceremony on the campus of Southern University of Science and Technology, a truck carrying 600,000 anti-fog alcohol wipes and 20,000 bottles of anti-fog alcohol spray set off to help Wuhan, Hubei.
This batch of wipes and sprays is a batch of anti-fog new materials. Shenzhen Nanke New Material Technology Co., Ltd., co-founded by Sun Dazhen, associate professor of the Department of Materials Science and Engineering of SUST, and Zhang Zhi, the first undergraduate graduate of SUST, Sun Dayao's research group of students' entrepreneurial teams worked together to urgently research and develop the system.
Zhang Zhi told a reporter from Beijing Youth Daily that the fogging of the goggles is caused by the formation of small water droplets due to the cold vaporization of water vapor on the lens and other surfaces. The light is scattered, resulting in blurred vision. The wet wipes developed by their team added a nano-hydrophilic material. After wiping the wet wipes, a durable transparent hydrophilic protective film can be formed on the surface of the lens. This layer of protective film will reduce the surface tension of the water droplets, making the small water droplets form a water film, greatly reducing the possibility of light being scattered, thereby eliminating fog. And the team added 75% alcohol to the solvent, which gave the wipes a disinfecting effect. Zhang Zhi said that the combination of anti-fog and disinfection effects is not available in current products on the market. Zhang Zhi said that the anti-fog effect can be maintained for at least 24 hours after wiping. In theory, one wipe can wipe one or two goggles, and the 600,000 wipes donated this time can wipe 600,000 goggles. This does not include the 20,000 bottles of anti-fog disinfection spray.
Zhang Zhi introduced that after the successful development of new materials, the first batch of products made 100 cans of wipes, of which 50 cans were donated to the Second Affiliated Hospital of SUSTC (Shenzhen Third People's Hospital). Medical staff responded well to the first products. Therefore, the team decided to expand production capacity to support Wuhan. The raw material of wet wipes is non-woven fabric, and non-woven fabric is also the raw material of masks, so it is very scarce. After contacting multiple units, they finally purchased non-woven fabrics from the Northeast and shipped them to Shenzhen by air. School departments recruited staff and team members to reinforce teams and became workers for a few days. In the end, they produced 10,000 barrels of wet wipes and 20,000 bottles of spray in less than five days.
On the evening of February 27, these supplies have been delivered to the first-line hospitals for anti-epidemic treatment in Wuhan.
