| Résumé : |
Polyvinylidene fluoride (PVDF) nanofibers doped with anion powder (AP) were prepared by electrospinning to efficiently sieve PM 2.5 and robustly release anions. Fiber morphologies formed by subtly regulating the mass fraction of AP were observed using the scanning electron microscope (SEM), and the air filtration property and the anion release capacity of the PVDF nanofibers were investigated. The results show that the average fiber diameter decreases rapidly then increases with the increasing AP mass fraction. AP particles aggregate on fiber surface when the mass fraction of AP reaches 9 wt.%.The filtration efficiency and the airflow resistance rise initially and then drop. The quality factor achieves the maximum and the anion release amount enhances significantly when the mass fraction of AP is 3 wt%. |
