“…Air pollution has always been a problem in human life because various gaseous pollutants (e.g., ultrafine particles) can cause a range of physical health problems when they enter the human respiratory system. , Respiratory infections caused by airborne viruses have also been a recurring concern. , Masks, as a type of personal protective equipment (PPE), can block harmful dust and respiratory droplet aerosols to reduce the risk of viral exposure and infection. , The key filter layer of the mask is usually manufactured by melt-blown or electrospinning, in which the fiber diameter of the PP filter membrane manufactured by the melt-blown method is generally in the range of 0.5–10 μm, which makes it difficult to rely on the mechanical interception of fibers to block ultrafine particles, and it also needs to be processed by electret treatment to attach an electric charge to obtain the electrostatic adsorption capability. , Electrospinning has a wide range of applications in tissue engineering scaffolds, energy production, human health protection, catalysis, and filtration. − …”
