Abstract

In the last ten years, the market and studies related with nanofibers are considerably increasing in the areas such as filtration, energy harvesting, medical textile. Electrospinning is one of the most widely used techniques for nanofiber production. Mainly, two different types of electrodes in the electrospinning process are used: one is the conventional narrow nozzle and the other is the nozzleless system. Conventional narrow nozzle is not preferred at industrial applications due to several problems such as low productivity, non-homogeneous coating and clogging. It is mostly preferred at laboratory applications, because of low price, wide production range and easy use. However, main disadvantages of nozzle-less system are high price (cost) and narrow production flexibility (range) compared to conventional narrow nozzle system. In this study, new novel nozzle prototype has been designed and studied to eliminate the disadvantages of conventional narrow nozzle system. From trials, it has been seen that production increased about 3 times compared to conventional narrow nozzle system, while homogenous coating could be obtained without clogging problem. It has also very low cost compared to nozzle-less system

Özet

Geçtiğimiz son 10 yıl içerisinde, nanolif ile ilgili çalışmalar ve pazar payları (filtre, enerji, tibbi tekstil vb alanları da kapsayacak şekilde) hızlı bir şekilde artmaktadır. Elektroeğirme sistemi, yaygın olarak kullanılan nanolif üretim tekniklerinden biridir. Temelde, elektroeğirme sisteminde iki tip elektrot kullanılmaktadır, şöyle ki; dar uçlu (iğne tipli) nozül sistemi ve nozülsüz sistem. Konvansiyonel dar uçlu nozül sistemi endüstriyel ölçekli üretimlerde, bazı dezavantajlarından ötürü (düşük üretim, homojen olmayan kaplama ve uçların sıklıkla tıkanması gibi) pek tercih edilmemektedir. Diğer taraftan, dar uçlu nozül sistemlerin, düşük maliyeti, oldukça esnek ve çok çeşitli üretim tiplerini üretebiliyor olması ve kullanım kolaylığı, laboratuar ölçekli uygulamalarda tercih edilmesine sebebiyet vermektedir. Nozülsüz sistemin en temel dezavantajı ise oldukça yüksek bir fiyata sahip olması ve üretim esnekliğinin (çeşitliliğinin) dar uçlu nozül sistemindeki kadar geniş olmamasıdır. Bu çalışmada, konvansiyonel dar uçlu nozül sisteminin dezavantajlarını yok edecek şekilde yeni bir prototip nozül sistemi dizayn edilmiştir. Gerçekleştirilen deneysel çalışmalar sonucunda, konvansiyonel dar uçlu nozül sistemine kıyasla yaklaşık 3 kat üretimin arttığı, son derece homojen yüzey kaplamanın, nozül tıkanması ile karşılaşmadan gerçekleştiği ve nozülsüz sisteme kıyasla oldukça düşük bir maliyete sahip olabileceği görülmüştür
