This study investigates the influences of key processing parameters on the formation of tin oxide (SnO2) fibers mat using the electrospinning technique. By systematically varying the annealing temperature, polyvinylpyrrolidone (PVP) concentration, and applied voltage. In this work examines the impacts on the crystallinity, morphology, and diameter of the resulting SnO2 fibers mat. Electrospun SnO2 concentrations fibers mat were produced with annealing temperatures ranging from 800°C to 1200°C, PVP of 8 wt% to 12 wt%, and applied voltage range 9kV to 18kV. X-ray diffraction (XRD) analysis confirms the formation of phase pure cassiterite SnO2 after calcination at 1200°C for 2 hours. Digital Microscope reveals as-spun SnO2 fibers mat diameters measurement and morphology. Lower PVP concentrations promote beaded morphologies and as applied voltage was increased, hence long SnO2 chains. By establishing structure-processing correlations, this work enables a good strategy for SnO2 nanostructures. © 2023 IEEE.
