In 2020, the Coronavirus (COVID-19) epidemic has swept the world, and masks have become a necessity for people to fight the epidemic. A few days ago, HKKJ Filter Material Technology Group announced the development of the world's strongest polymer nano-film, which can be used to make transparent masks with a filtering performance exceeding N95 masks to facilitate communication among people with disabilities.
According to the CTO of HKKJ, although this film is light, thin, soft and breathable, it is 25 times stronger than stainless steel of the same quality, and it is waterproof. She said that in the future, by adjusting the size of the pores, this nano-film can also be used in other cutting-edge technology products such as wound waterproof dressings, wearable devices, seawater desalination, and solar cells.
