Abstract

See full text

The present disclosure provides an electrospinning method for fabricating a nanofiber air filter with a minimized pressure drop. The method comprises following steps: S1. 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; S2. 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(Vm, tn) and pressure drop ΔP(Vm, tn), Vm is electrospinning voltage and tn is electrospinning time; and S3. finding optimal electrospinning voltage Vopt and optimal electrospinning time topt, such that an air filter fabricated by Vopt and topt can achieve target particle removal efficiency ηtar and minimized pressure drop ΔPmin.
