Effect of Morphology of Nanostructures to Filter Ultrafine Particles
Kimmer, D. ; Vincent, I. ; Fenyk, J. ; Petráš, D. ; Zatloukal, M. ; Sambaer, W. ; Ždímal, Vladimír
Selected procedures permitting to prepare homogeneous nanofibre structures of the desired morphology by employing a suitable combination of variables during the electrospinning process are presented. A comparison (at the same pressure drop) was made of filtration capabilities of planar polyurethane nanostructures formed exclusively by nanofibres and space nanostructures having bead spacers or structures formed by a combination of micro-and nanofibres, through which ultrafine particles of ammonium sulphate 20 - 400 nm in size were filtered. The structures studied were described using a new digital image analysis technique based on black and white images obtained by scanning electron microscopy.
