Influence of Fast Drying on the Morphology of α-Fe 2 O 3 and FeMnO 3 /α-Fe 2 O 3 Fibers Produced by Solution Blow Spinning

α-Fe O and FeMnO /α-Fe O 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.
