With the rapid development of urbanization and industrialization, air pollution is increasingly harmful to life on earth. At present, purifying polluted air through functional filter materials is an effective but still challenging and important strategy. But there was the problem that the air filter protection materials are easy to get wet, which will reduce the filtering effect and cause the service life to decrease. In this study, we used PU fiber membrane prepared with electrospinning as the substrate, fluorinated silica nanoparticles (F-SNs) and quaternary ammonium salt silica particles (Q-SNs) were used as functional particles, PDMS were used as adhesive to prepare hydrophobic and anti-fouling F/Q-SNs-PU fiber membrane through coating. F/Q-SNs-PU fiber membrane exhibited excellent hydrophobic stability, excellent anti-fouling and self-cleaning ability, and filtration effect. Therefore, F/Q-SNs-PU fiber membrane can effectively alleviate the air filtration problem in high humidity environment by virtue of its excellent hydrophobic anti-fouling performance and filtering effect.
