Abstract：In recent years, PM2.5 particles have become the main health killer in the air pollution.In order to minimize the harm of particulate matter, people usually use masks to prevent inhalation of PM2.5 particles.However, these masks are not able to filter out the PM2.5 particles because of their huge pores.As for those with relatively good barrier properties, the air permeability is often poor, which can cause other potential diseases.In this paper, a kind of polysulfone nanofibers were prepared by electrospinning for respirator filter.The characteristics of this kind of nano material are shown by electron microscope scanning, permeability test and PM2.5 barrier test.The results show that the material of the nano fiber mask can effectively filter the PM2.5 particles, and it can keep good air permeability.It is considered that the nano scale fiber, which has the same permeability as the ordinary face masks, greatly reduces the porosity of the fiber.
