Çörekotu Yağı İçeren Poliüretan Nanolifli Yüzeylerin Morfolojik Özellikleri Üzerine Bazı Proses Parametrelerinin Etkilerinin Araştırılması

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 (BSO) 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.

The Effect of Essential Oil on Fiber Morphology and Surface Properties in Coaxial Nanofibers

“…The reason why different oils add different conductivity to the polymer solution is the chemical bonds in their structures. As the number of ions in the solution increases, the conductivity of the solution increases (Aras et al, 2019). Black pixels (considered empty space) in segmented images as shown in Figure 3 were analyzed in ImageJ using the Analyze Particles command, which counts the number of pixels in individual black pixel clusters.…”
