In this study, PVDFfibers were produced using centrifugal spinning (CS) and solution blowing (SB) methods, and their comparative characterization has been carried out. While defect-free mats composed of smoother, thicker and more uniform fibers were obtained with the CS method, mats containing fine and crimped fibers and highly entangled fiber bundles were produced with the SB method. The average fiber diameters were measured as 0.827 + 0.365 mu m for fibers produced by CS and 0.356 + 0.168 mu m for those obtained by SB. It was determined that the PVDFfibers produced by both methods predominantly exhibited the beta-phase with a small amount of the alpha-phase. In the production where the same amount of solution was used, fiber mats of similar thickness were obtained, while the basis weight of the mats produced by the CS method was approximately half that of the SB samples. The SB samples, containing both thin fibers and thick fiber bundles, exhibited a more compact structure. Therefore, the filtration efficiency of the samples with the same thickness was higher for SB. However, mats with the same basis weight showed similar filtration efficiency. These results indicate that both methods are suitable to produce PVDFfibers. The CS method enables the production of thicker but defect-free fibers, and the production methods do not significantly affect the fiber's crystalline structure. Additionally, fiber diameter, morphology, and basis weight of the mats significantly influence filtration performance. The compact structure of the fibrous mat from SB resulted in a higher filtration efficiency.
