Abstract Simultaneous capture of different air pollutants including aerosols and volatile organic compound (VOC) is demonstrated using composite polyacrylonitrile (PAN)/β-cyclodextrin (β-CD) nanofiber membrane. Aerosol filtration along with VOCs adsorption in one step remains a challenge due to differences in the physical and chemical properties of these air pollutants. PAN/β-CD composite electrospun nanofiber membranes (ENMs) were produced with different concentrations of β-CD. The surface modification of the composite ENM was confirmed by X-ray photoelectron spectroscopy (XPS), field emission-scanning electron microscopy (FE-SEM) and water contact angles. PAN/β-CD composite ENMs showed excellent air filtration performance (>95% filtration efficiency with a relatively low pressure drop of 112 Pa). Formaldehyde (HCHO) adsorption was determined using a simple jar method and xylene adsorption by UV spectroscopy. HCHO and xylene adsorption found better by 66% and 73%, respectively, compared to pristine PAN ENM despite a reduction in fiber surface area. The composite ENMs were found to be nontoxic to human lung cell line, suggesting that it is a good candidate for respiratory filter media for simultaneous air filtration and VOC adsorption.
