Abstract
The porosity of electrospun mat and scaffolds reaches often more than 90 %, [1] which gives an enormous advantage in skin or would care dressing. Apart porosity and meshes geometry the key parameters in these biomedical applications are surface properties, which we control via single step electrospinning process by alternating voltage polarities in electrsopinning. [2] Voltage polarity defines the charge accumulated on the surface of the liquid jet and the surface of the fibers. Positive polarity attracts negatively charged groups to fibers’ surface, whereas negative polarity moves the negatively charged functional groups away from the surface, while the polymer solution is in the liquid form. This way we can control the surface chemistry, [3] wettability [2] and additionally surface potential of electrospun polymer fibers. [4, 5] Within our research we characterized so far surface chemistry of PCL and PVDF fibers using x-ray photoelectron microscopy (XPS) and surface potential with Kelvin probe force microscopy (KPFM). We proved the significant effect of surface potential on cell integration with the fibers meshes and cells development for the regeneration processes [5] increasing their responses in medical treatments.
