Abstract

Tin oxide microfibers were created through electrospinning using a precursor solution consisting of poly(ethylene oxide) (PEO) and chloroform (CHCl3) which was then mixed with its tin precursor, dimethyldineodecanoatin (C22H44O4Sn). Since the conductivity of SnO2 is affected by any chemisorbed oxygen molecules on its surface, this semiconductor has high potential for use as a gas sensor for both oxidizing and reducing gases. Due to the fact that a greater surface area will produce gas sensors with improved sensitivity, work is underway to reduce the fibers size into the nanoscale range. Thus, this study explores various electronic transport characteristics—such as the conductivity and magnetoresistance—of the tin oxide microfibers. Additionally, the composition and phase of the fibers were characterized through XRD and Raman spectroscopy.
