Abstract
Electrospinning is becoming the main production method of nano- and microfibers with scaling up possibilities. This is a cost-effective method as fiber’s properties can be controlled with the experimental setting avoiding any additional postprocessing or chemical treatments. Due to the high surface area, unique surface properties, and porosity, electrospun fibers find many applications. For example, we are able to control the wetting of fibers via their roughness1, which can be also tuned to biomimic spider webs known to be natural fog collectors2. Moreover, the ability to control surface chemistry leads to significant enhancement of the triboelectric and piezoelectric performance of electrospun mats3. Surface properties of the fibers are also critical in medical applications, regulating cells adhesion, proliferation and mineralization towards tissues formation4, 5. The variety of process parameters during the production of electrospun fibers can be optimized to tailor the morphology and surface properties of produced membranes. Alternating of voltage polarity reorientate functional groups in polymer chains as charges accumulate at the surface of the liquid jet during electrospinning6. To verify the surface morphology and potential we applied advanced microscopy technique and to analyzed surface chemistry we used x-ray photoelectron microscopy. The correlations between surface chemistry and properties were obtained for a few polymers such as PCL, PVDF, and PMMA. Our studies open new creative solutions for manufacturing surfaces without any chemical modification of fibers surfaces for energy and water harvesting and most importantly in tissue engineering.
