Professor Liang Huanfang, a professor of mechanical engineering at the Hong Kong Polytechnic University, spent 9 years developing a multi-layered nanofiber filter that uses masks, particles, and bacteria to block 80% of the particles, which is comparable to 95% of the N95. Lighter and thinner, it makes breathing easier. This invention was recently awarded a special prize and a gold medal at the International Invention Exhibition in Geneva and is expected to be put into production this year. Liang Huanfang developed a multi-layer nanofiber filter material composed of a plurality of nanofiber thin layers. Each layer has a built-in non-woven fabric, which can effectively block fine particles such as diesel particles, laser printer particles, and bacteria into the human body. Prevent various chronic diseases. Liang Huanfang said that traditional masks can only block about 28% of the 300 nanometer-sized particles, while masks made using multilayer nanofiber filters can block up to 80% of particles. Liang Huanfang said that traditional masks are made of multiple materials and their mask materials are much thinner. With the same protective force, the production cost is lower, so the selling price will be lower than the masks on the market. In addition, Liang Huanfang pointed out that the mask can have additional functions, such as killing bacteria, so that masks can maintain efficacy after multiple uses, and even can convert gaseous pollutants into harmless substances. This filter material can also be used as a filter to produce indoor air vents, such as air conditioners, for a wide range of applications. According to reports, Liang Huanfang is currently negotiating with a number of overseas manufacturers and hopes to introduce products to the market this year.
