At present, the situation of air pollution is still serious, and research on air filtration is still crucial. For the nanofiber air filtration membrane, the diameter, porosity, tensile strength, and hydrophilicity of the nanofiber will affect the filtration performance and stability. In this paper, based on the far-field electrospinning process and the performance effect mechanism of the stacked structure fiber membrane, nanofiber membrane was prepared by selecting the environmental protection, degradable and pollution-free natural polysaccharide biopolymer pullulan, and polyvinylidene fluoride polymer with strong hydrophobicity and high impact strength. By combining two kinds of fiber membranes with different fiber diameter and porosity, a three-layer composite nanofiber membrane with better hydrophobicity, higher tensile strength, smaller fiber diameter, and better filtration performance was prepared. Performance characterization showed that this three-layer composite nanofiber membrane had excellent air permeability and filtration efficiency, and the filtration efficiency of particles above PM 2.5 reached 99.9%. This study also provides important reference values for the preparation of high-efficiency composite nanofiber filtration membrane.

Oily particulate matter pollution and bacteria pose a serious threat to human health and have drawn widespread attention. Herein, an Ag‐doped nylon 6 multi‐stage structured antibacterial nanofiber membrane (PA6&Ag MSNM) for effective air filtration of fine oily particulate matters was fabricated by adding a certain amount of tetrabutylammonium hexafluorophosphate (TBAHP) and silver nitrate (AgNO3) into PA6 solution via one‐step electrospinning. The fabricated PA6&Ag MSNM is composed of coarse trunk fibers and fine branching fibers, which exhibits high filtration efficiency for oily particulate matters and low pressure drop, with an average filtration efficiency of 99.92% for oily particles of 0.20 ~ 4.59 μm and a low pressure drop of 386 Pa. In addition, the fiber membranes possesses excellent antibacterial properties due to the doping of Ag. The prepared multi‐stage electrospun nanofiber membrane may provide a versatile strategy for designing new antibacterial air filtration materials, which would have broad application prospects.
