Research progress of filtering material for medical mask

Medical mask filtering materials have problems including high respiratory resistance, short effective time of electrostatic adsorption caused by easy loss of charge in the filtering materials, and the disposable use of the filtering materials. This paper reviewed and summarized the research progress of the medical mask filtering materials. According to the history of mask development, the evolution of the meltblown superfine fiber nonwovens, nanofiber membranes, multifunctional composite nanofiltration materials and their preparation technology were analyzed. From the perspective of patent application, new materials and new technologies, the development trend of filtering materials for medical masks was discussed. It is believed that the nanoscale filtering materials, the filtration with multi-layer functional materials and safe reuse of filtering materials represent the future research and development directions for medical mask materials.
