Current worldwide epidemics, such as the COVID-19 pandemic and PM pollution, necessitate immediate preventative measures. COVID-19 cannot spread without the use of nanofibrous air filter membranes that can trap PM0.3. Herein, a highly efficient nanofibrous air filter membrane based on amphiphilic poly(vinylidene chloride)-graft-poly(oxyethylene methacrylate) (PVDF-g-POEM) double comb copolymer was fabricated via ATRP and electrospinning. The amphiphilic PVDF-g-POEM double comb copolymer nanofibrous air filter membrane obtained a low air resistance of 4.69 mm H2O and a high filtration efficiency of 93.56 %.
