Abstract
The present disclosure provides an electrospinning method for fabricating a nanofiber air filter with a minimized pressure drop. The method comprises following steps: S. dissolving a specified amount of powder polymer material in a solvent, and magnetically stirring a resulting solution; adding the solution to a syringe connected with a microneedle by a plastic tube, and pumping the solution by the syringe into an electrospinning machine; S. allowing the electrospinning machine to work under a high voltage, such that the solution generates nanofibers; the nanofibers are interweaved to fabricate air filters for removing particles in air with a particle removal efficiency η(V, t) and pressure drop ΔP(V, t), Vis electrospinning voltage and tis electrospinning time; and S. finding optimal electrospinning voltage Vand optimal electrospinning time t, such that an air filter fabricated by Vand tcan achieve target particle removal efficiency ηand minimized pressure drop ΔP.
