PAN Bazlı Nanofiberlerin Elektroeğirme ile Üretiminde Proses Değişkenlerinin İstatistiksel Modellenmesi

In this study, the effects of the electrospinning operating parameters such as flow rate (1-5 ml/h), voltage (15-30 kV), and distance to the collector (100-200 mm) on the physical properties of PAN-based nanofibers were investigated statistically by applying the central composite design method. The minimum nanofiber diameter was found to be 366.5 nm, under operating conditions of 5 ml/h flow rate, 30 kV, and 100 mm distance to the collector. Experimental conditions of 15 kV, 5 ml/h flow rate, and a 200 mm distance to the collector, a maximum porosity value of 0.446 was obtained. Similarly to the porosity, the water absorption capacity (WAC) value did not show a linear increase, and the maximum absorption capacity was calculated as 5712%, and at that point where the diameter is relatively large and the porosity is low.
