The emergence of the new coronavirus has disrupted the medical-grade protection market. In the New Year of 2020, how the protection industry can truly release production capacity during the special period and how to deploy to make up for the huge market gap has also become a national concern. For ordinary citizens who are about to return to work, the most urgent need must be masks. It is reported that the masks that can play a role in virus protection mainly include medical surgical masks and N95 masks. The main material that brings the virus filtering effect to these two masks is the ultra-fine and electrostatically charged inner filter cloth made of polypropylene-meltblown non-woven fabric. However, electrostatic adsorption masks have a huge disadvantage. The electrostatic content will gradually decrease with the production, packaging, leaving the factory, transportation, and use, and the protection efficiency will decline. To this end, the Chinese Society of Composite Materials has proposed a new direction for the development of epidemic prevention-PTFE nano-film masks. Nano anti-bacterial masks are similar to ordinary medical masks, but also include outer layer, middle layer, inner layer, ear hooks, nose clips, etc. The special feature is that the middle layer is made of nano-membrane with a smaller pore size (100-200 nanometers) , Generally PTFE material. The PTFE film prepared by one-way or two-way stretching method has a spider web-like microporous structure on the surface. The three-dimensional structure has very complicated changes such as network connection, hole inlay, and hole bending, so it has excellent surface filtration. Features. Nano masks produced using this material have the characteristics of high barrier efficiency, long service life, light and thin air permeability, and are a new direction for the development of masks in the future. However, currently, PTFE nano-film masks are affected by price factors and cannot completely replace traditional masks.
