Abstract

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.

Özet

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.
