Black seed and its extracts have been used in alternative medicine since
ancient times. The aim of this study is to produce and characterize composite
nanofibrous surfaces by electrospinning with the addition of black seed oil
with different concentrations into the thermoplastic polyurethane polymer for wound dressings. During electrospinning the flow rate, and the
distance between the needle and the collector were changed. The morphologies of
the surfaces were analyzed by scanning electron microscopy (SEM). The nanofiber diameters, pore size and porosity of the nanofibrous mats
were determined. The presence of black seed oil was investigated by FTIR
analysis and the wettability of the surfaces was examined by contact angle
measurements. As a result, optimum electrospinning process parameters and the
most appropriate black seed oil concentration were determined to produce
continuous, uniform and bead-free nanofibers.

Çörekotu
tohumu ve ondan elde edilen ekstraktlar antik çağlardan beri alternatif tıp
alanlarında uygulanmaktadır. Bu çalışmada, termoplastik poliüretan polimeri
içerisine farklı konsantrasyonlarda çörek otu yağı ilave edilerek, elektro
çekim yöntemi ile yara örtüsü amaçlı nanolifli kompozit yüzeyler üretilmesi ve
karakterize edilmesi amaçlanmıştır. Üretim esnasında besleme ünitesi ile
toplayıcı arasındaki mesafe ve besleme oranı değiştirilerek; elde edilen
yüzeylerin morfolojileri taramalı elektron mikroskopu (SEM) ile analiz
edilmiştir. Nanolifli yüzeylerin, nanolif çapı, gözenek boyutu ve
gözeneklilikleri tayin edilmiştir. Nanolifli yapı içerisindeki çörek otu
yağının varlığı FTIR analizi ile ve yüzeylerin ıslanabilirlik seviyesi temas
açısı ölçümleri ile incelenmiştir. Sonuç olarak; sürekli, üniform ve boncuk
içermeyen nanolifler elde etmek için çörekotu yağı katkısı için en uygun
konsantrasyon ve optimum elektro çekim proses parametreleri belirlenmiştir.
