This study aimed to produce electrospun nanofibers from a polyvinyl butyral polymer (PVB) solution enriched with red and grey selenium nanoparticles. Scanning electron microscopic analysis was used to observe the samples, evaluate the fiber diameters, and reveal eventual artifacts in the nanofibrous structure. Average fiber diameter is determined by manually measuring the diameters of randomly selected fibers on scanning electron microscopic (SEM) images. The obtained nanofibers are amorphous with a diameter of approximately 500 nm, a specific surface area of approx. 8 m g, and 5093 km cm length. If the red and grey selenium nanoparticles were produced in powder form and suspended to the ethanolic solution of PVB then they were located inside and outside the fiber. When selenium nanoparticles were synthesized in the PVB solution, then they were located only inside the fiber. These nanofiber sheets enriched with selenium nanoparticles could be a good candidate for high-efficiency filter materials and medical applications.
本研究旨在从富含红、灰硒纳米粒子的聚乙烯醇缩丁醛（PVB）溶液中制备电纺纳米纤维。扫描电子显微镜分析用于观察样品，评估纤维直径，并揭示纳米纤维结构中的任何人为制品。平均纤维直径通过手动测量扫描电子显微镜（SEM）图像上随机选择的纤维的直径来确定。所得纳米纤维为无定形，直径约为 500nm，比表面积约为 8m2g-1，长度为 5093kmcm。如果红、灰硒纳米粒子以粉末形式生产并悬浮在 PVB 的乙醇溶液中，则它们位于纤维内外。当硒纳米粒子在 PVB 溶液中合成时，它们仅位于纤维内部。这些富含硒纳米粒子的纳米纤维片可能是高效过滤材料和医疗应用的良好候选材料。
