| Summary: | 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. |
