Bu çalışmanın amacı, elektro çekimde toplayıcı olarak farklı kalınlık ve malzemelerdeki metal plakalar kullanılarak üretilen liflerin morfolojik özelliklerinin incelenmesidir. Bunun için 1 mm, 5 mm, 10 mm kalınlığında yuvarlak şekilli alüminyum ve bakır levhalar kullanılmıştır. Sonuçlar, alüminyum toplayıcılara kıyasla bakır toplayıcılar kullanıldığında çok daha ince liflerin elde edildiğini göstermektedir. Toplayıcı kalınlığının etkisi incelendiğinde ise toplayıcı kalınlığı arttıkça lif inceliğinin arttığı gözlenmiştir. Ayrıca, alüminyum toplayıcı ve daha ince toplayıcı kullanıldığında toplayıcı üzerindeki liflerin toplanma alanının çok daha geniş olduğu gözlenmiş, bu da elektrolif çekiminde toplayıcı malzeme ve toplayıcı kalınlığının lif dizilişini ve lifler arası mesafeyi etkilediğini göstermektedir. Toplayıcı kalınlığının ve toplayıcı malzeme tipinin etkisi ile deneysel sonuçlar ışığında doğrulanmasına ilişkin teorik bir yaklaşım da bu çalışmada yer almaktadır.

AN INVESTIGATION OF THE EFFECT OF COLLECTOR PLATE MATERIAL AND THICKNESS ON ELECTROSPUN FIBER FINENESS INCLUDING A THEORETICAL ANALYSIS

Öz

The aim of this study is to examine the morphological properties of fibers produced by using metal plates of different thickness and materials as collectors in electrospinning. For this, circular shaped aluminum and copper plates of 1 mm, 5 mm, 10 mm thickness were used. The results show that much finer fibers were obtained when copper collectors are used compared to aluminum collectors. When the effect of collector thickness is analyzed, it was observed that fiber fineness increased as the collector thickness increased. In addition, it was observed that collection area of fibers on collector is much larger when aluminum collector and thinner collector is used showing that collector material and collector thickness affect fiber arrangement and interfiber spacing in electrospinning. A theoretical approach is also included in this work regarding effect of collector thickness and collector material type together with its verification in the light of experimental results.
