Abstract :In the study, the morphology of the fibers produced by electrospinning using polyacrylonitrile polymer was investigated by changing the distance between needle and collector plate. For this purpose, 8 cm, 13 cm, 18 cm, 23 cm, 28 cm distances were studied. With the experimental parameters applied in the study at 8 cm and 13 cm distances, continuous fiber formation did not occur and a dense dripping was formed. When the distance was increased to 18 cm, fiber production started without interruption. The diameters of the nanofibers were measured by scanning electron microscopy (SEM), and the SPSS program was used to compare the diameter values obtained statistically. When the distance is 18 cm, the average diameter of the produced nanofibers varies between 509.96-572.48 nm, while this value varies between 460.90-522.01 at 23 cm and 399.67-462.48 at 28 cm. It was observed that the fiber diameter decreased as the distance between needle and collector plate increased. As the distance decreases, the fibers are gathered together more on the paper surface. Therefore, a thicker fiber layer was obtained when the distance was 18 cm. In addition, nanofiber fineness optimization was carried out according to the Taguchi method with two parameters using the Minitab program.Keywords : Anahtar kelimeler: elektrolif çekimi, elektrotlar arası mesafe, nanolif çapı, nanolif morfolojisi, optimizasyon.
