Hongkong Universities Have Developed Nanofiber Masks

A multi-layer nano fiber respirator, which can be used for effective protection of fog and haze, was developed by researchers from universities in Hongkong. In October 23rd, it signed a "marriage" with relevant enterprises at Hong Kong Polytech University in the afternoon to promote innovative technology to achieve industrial application. Its goal is to make prototype samples of nano fiber respirators after half a year, and the official products will be 1 years later.

　　 Hong Kong The research team led by Professor Liang Huanfang, Professor of innovative products and technology at the University of science and technology, has been focusing on the nanofiber technology platform and its filtration and separation technology for many years. It is committed to blocking the research of suspended particles which can be called "invisible killer" of human health. It includes PM10 (suspended particles with diameter of 10 microns or below) and PM2.5 (diameter 2.5 micron or below suspended particles) or even ultrafine particles with diameters of 1 microns or less.

Liang Huanfang said that his scientific research team used advanced nanotechnology to make natural or synthetic materials with only 1/500 hair (about 0.1 millimeters) of fine nanofibers. Based on this research, the multi-layer nano fiber respirator can block 90% aerosols suspended in the air, even if the aerosol is less than 0.3 microns, it can also filter effectively. At the same time, through the new invention of the team, dividing the most suitable nanofibers into multiple thin layers, there are breathable layers between two thin layers, which can provide plenty of flow space for the air, so that the users of the nanofiber mask can breathe freely and can be used for outdoor activities.

If this is the case Nanometer Fiber technology can effectively prevent bacteria and viruses less than 1 microns, and can provide more protection for front-line medical staff. Liang Huanfang said that in addition to personal protective equipment, through the mixed application of nanofiber filtration and purification technology, it can also purify the air in buildings and aircraft, automobiles, trains, ships and other cabin, improve and improve indoor air quality.

In the afternoon, Hongkong Science and Engineering The University signed the agreement on the commercialization and cooperation of nanofiber technology with the company. The cooperative company said that it was optimistic about the multi-purpose and potential market of nanofiber technology, and decided to invest more than 10 million HK dollars in R & D products.

The nanofiber technology developed by Liang Huanfang team has recently won the gold medal of the forty-second Geneva International Invention Exhibition and the special award of Ministry of education of Romania.
