One of the most promising nanostructures, core/shell structured co-axially electrospun nanofibers have been widely used in many applications such as self-healing, wound dressing/healing, drug and gene delivery and tissue engineering. Core/shell structured nanofibers have generally been produced using the coaxial electrospinning method. In this study, the coaxial electrospinning using the double injectors technique was applied for investigating the processing parameters for the PVA/Nigella seed oil solutions affecting the core/shell nanofiber morphology. Results showed that the processing parameters, such as the flow rate, voltage difference and solution concentration had significant effects on the core/shell nanofiber morphology. Nanofiber morphologies were characterized using SEM-Scanning Electron Microscopy techniques.

核/壳结构同轴电纺纳米纤维是最有前途的纳米结构之一，已广泛用于许多应用中，例如自我修复，伤口包扎/修复，药物和基因递送以及组织工程。核/壳结构的纳米纤维通常使用同轴电纺丝法生产。在这项研究中，使用双注射器技术的同轴电纺被用于研究影响核/壳纳米纤维形态的PVA / Nigella种子油溶液的加工参数。结果表明，流速，电压差和溶液浓度等加工参数对核/壳纳米纤维的形貌有显着影响。使用SEM-扫描电子显微镜技术表征了纳米纤维的形态。
