ZnO-Impregnated Polyacrylonitrile Nanofiber Filters against Various Phases of Air Pollutants

The incorporation of metal oxide nanoparticles (NPs) in fiber filters is an effective approach to enhance the specific surface area and roughness fiber, hence improving their efficiency for fine dust capture other gas treatment or biological applications. Nevertheless, uneven distribution NPs limits practical In this study, a commercial silane coupling agent (3-methacryloxypropyltrimethoxysilane) was used improve dispersion zinc (ZnO) thin polyacrylonitrile fibers. Scanning electron microscopy (SEM) revealed that fibers incorporating silane-modified exhibited better than those prepared with pristine ZnO NPs. modification enhanced area, roughness, porosity. particular, nanofiber filter 12 wt% modified 0.5 g per maintained filtration 99.76% low pressure drop 44 Pa, excellent antibacterial activity, could decompose organic methylene blue dye 85.11% under visible light.
