N2 - We have produced woven/polyamide 6 (PA6) nanofiber composites to achieve high filtration efficiency without causing excess pressure drop. We have controlled electro spinning condition and polymer concentrations and investigate their effect on nanofiber web structures, filtration properties and air permeability. We successfully produced bead-free smooth nanofibers webs with average fiber diameter of as small as 47nm. By depositing very thin layer of nanofiber web (basis weight ranges of 0.05-0.5g/m2), we have achieved at least 200% improvement of filtration efficiency with only 20% increase in pressure drop. We also produced nanofiber/metal oxide nanoparticle composite fibers with single step in situ electrospinning to functionalize PA6 nanofiber webs. Al2O3, TiO2, ZnO and Fe2O 3 nanoparticles with different particle size and forms were used and their effects of nanofiber morphology were investigated. We have found metal oxide nanoparticles incorporate in PA6 nanofiber web provide photocatalytic reaction.
