Abstract

α-FeO and FeMnO/α-FeO fibers were successfully prepared via Solution Blow Spinning (SBS). The effect of drying during the SBS process on fiber morphology was evaluated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and N adsorption-desorption isotherms. A slow drying promoted continuous fibers with rough surfaces and lower average diameters. However, fast drying enabled the production of fibers with low densification and many surface pores with higher BET-specific surface areas. The porous fibers produced have potential applications in energy generation and storage.

摘要

通过溶液吹纺（SBS）成功制备了α-FeO和FeMnO/α-FeO纤维。通过扫描电子显微镜（SEM）、透射电子显微镜（TEM）和N吸附-脱附等温线评估了SBS过程中干燥对纤维形态的影响。缓慢干燥促进了表面粗糙且平均直径较小的连续纤维的形成。然而，快速干燥能够生产出致密化程度低且具有许多表面孔隙、BET比表面积较高的纤维。所制备的多孔纤维在能量产生和存储方面具有潜在应用。
