Abstract: | Electrospun fiber webs were prepared at various spinning conditions. The effect of electrospinning parameters on fiber morphology
and filtration performance of electrospun webs was investigated. The processing variables considered were only the applied
voltage and rotation speed of a drum type collector. The fiber diameter and mean pore size of the electrospun webs decreased
with increasing applied voltage and collector speed. Pressure drop and aerosol collection efficiency of the electrospun fiber
webs were increased with decreasing fiber and pore size. Additionally, it was found that the filtration performance of the
electrospun web was much greater than that of a commercial high efficiency air filter media made of glass fibers. |
