Abstract

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.

PAN Bazlı Nanofiberlerin Elektroeğirme ile Üretiminde Proses Değişkenlerinin İstatistiksel Modellenmesi

Abstract

Bu çalışmada, akış hızı (1-5 ml/sa), voltaj (15-30 kV) ve kollektöre olan mesafe (100-200 mm) gibi elektroeğirme çalışma parametrelerinin PAN bazlı nanofiberlerin fiziksel özelliklerine etkisi, merkezi kompozit tasarım yöntemi uygulanarak, istatistiksel olarak incelenmiştir. 5 ml/sa akış hızında, 30 kV voltajda ve kolektöre 100 mm mesafedeki çalışma koşullarında minimum nanofiber çapı 366,5 nm olarak bulunmuştur. 15 kV, 5 ml/sa akış hızı ve kolektöre 200 mm mesafe uzaklıktaki deney koşullarında, maksimum gözeneklilik değeri 0,446 olarak elde edilmiştir. Gözenekliliğe benzer şekilde, su tutma kapasitesi (STK) değeri doğrusal bir artış göstermemiş ve maksimum absorpsiyon kapasitesi %5712 olarak hesaplanmış ve bu noktada çapın nispeten büyük ve gözenekliliğin düşük olduğu nokta olarak belirlenmiştir.
