Abstract The novel PAN/PVDF-HFP/TiO₂ nanofibrous membranes with a high performance in PM_2.5 removal and high-temperature filtration were developed in this study under co-electrospinning-electrospray strategy, with PVDF-HFP/TiO₂ as the functional layer and polyacrylonitrile (PAN) as the base membrane. According to the results, the PHT20nanofibrous membrane achieved an efficiency of 99.8% in capturing particulate matters, a low pressure drop of 67Pa, excellent air permeability, and high thermal stability (to 200°C). Moreover, the results of self-cleaning tests showed that the superhydrophobic surfaces of the PAN/PVDF-HFP/TiO₂ nanofibrous membranes were resistant to dust particle contamination. To sum up, the multifunctional PPHT20 nanofibrous membrane developed in this study is an effective solution to dust removal at high temperatures.
