Abstract

In this study, the production of hollow Polybutylene Succinate (PBS)/Thermoplastic Polyurethane (TPU) nanofibers as biodegradable nanomaterials with improved mechanical properties were carried out by coaxial electrospinning method. The polymer solutions of pure PBS, pure TPU, and PBS/TPU blends (60/40, 40/60, 20/80 w/w) (as the shell) versus pure Polyvinylpyrrolidone (PVP) (as core) were put together for bi-component nanofibers production. The core structure of nanofibers was dissolved in distilled water. Thus, hollow nanofibers were obtained with the removal of PVP from the structure. Characterization studies (SEM, FTIR, and Tensile tests) of hollow nanofibers were performed. The morphological properties of PBS/TPU blends in ratios of 60/40 and 20/80 were observed as homogeneous and non-adhered fiber structures. It was determined that the hollow PBS/TPU (60/40) mat has the thinnest nanofibers. New bond formations within the interactions of substances as studied in the chemistry of blended electrospun webs were examined with FTIR analysis. Therewithal, this test showed the removal of PVP in the core of all nanofibers. It was observed that the adhered fibers increased the tensile stress and decreased the tensile strain at mechanical test results that were verified also by SEM views. It is suggested that the hollow nanofibers produced by this study can be used in the biomedical field as a biodegradable and breathable wound dressing

同轴静电纺丝法由PBS/TPU共混物制备中空纳米纤维

本研究采用同轴静电纺丝方法制备了中空的聚丁二酸丁二醇酯（PBS）/热塑性聚氨酯（TPU）纳米纤维，作为具有改善机械性能的可生物降解纳米材料。将纯PBS、纯TPU和PBS/TPU共混物（60/40、40/60、20/80w/w）（作为壳）与纯聚乙烯吡咯烷酮（PVP）（作为芯）的聚合物溶液放在一起用于双组分纳米纤维生产。将纳米纤维的核心结构溶解在蒸馏水中。因此，通过从结构中去除PVP获得了中空纳米纤维。对中空纳米纤维进行了表征研究（SEM、FTIR和拉伸试验）。观察到60/40和20/80比例的PBS/TPU共混物的形态特性为均匀和非粘附的纤维结构。确定中空PBS/TPU（60/40）垫具有最薄的纳米纤维。用FTIR分析检测了在混合电纺纤维网化学中研究的物质相互作用中的新键形成。此外，该测试显示在所有纳米纤维的核心中PVP被去除。在SEM视图也证实的机械测试结果中，观察到粘附的纤维增加了拉伸应力并降低了拉伸应变。本研究制备的中空纳米纤维可以作为一种可生物降解、透气的伤口敷料应用于生物医学领域
