This study focuses on combining graphene oxide, polyacrylonitrile, and polyimide to prepare PAN/GO/PI nanofibrous membranes for efficient air filtration. The as-prepared membranes demonstrate high filtration efficiency, low pressure drop, remarkable thermal stability, and excellent mechanical strength, making them suitable for various industrial applications and civil health needs.
Particulate matter (PM) pollution can severely affect human health. Currently, the most dangerous air pollutant is PM2.5 which refers to particles with a diameter less than 2.5 mu m. In order to mitigate the detrimental effects of PM2.5, there is an urgent demand for an air filter with improved performance. In this study, graphene oxide (GO), polyacrylonitrile (PAN), and polyimide (PI) are combined to prepare PAN/GO/PI nanofibrous membranes for efficient air filtration via electrospinning. The as-prepared PAN/GO/PI-6 nanofibrous membranes demonstrate high filtration efficiency (99.5%), low pressure drop (92 Pa), remarkable thermal stability (300 degrees C), and excellent mechanical strength. Built upon the above merits, this kind of nanofibrous membrane can account for widespread utilization in both industrial applications and civil health warrants.
