Production and Characterization of Air Filters with Nanofiber Layers Via Electro-Spinning Method

In thiss tudy, thesurface of different materials having pores in the macro size are covered by a nanofiber layer with the electro-spinning method in order to improve the filtering performance. Only microfiber filters could be effectivelyused as a filterlayercoated on thesurface of thenanofiber. The used filtration of micro particles between 25-85g/m^2 weighted micro fiber filters surfaces were covered by electrospinning method with nanofiber layer by the experimental parameters 21-30ml/h polymer solution feed flow rate and 28-32 kV applied voltage and electrod espacing 19-23cm. The five differentair filter samples ranging between 2-4 g/m^2 and nanofiber diameter between 77-200nm were obtained. Nano fiber layer weight, nanaofiber diameter, and the surface morfology changes with the changing parameters in the electro-spinning experiments and its effect on the manufactured samples were observed. In summary it seen that macro-porous materials can not be used as a nanofiber layer filter.
