Abstract

Zinc oxide (ZnO) / graphite composite nanofibers were fabricated via electrospinning method. The amount of graphite was varied and its effect on the diameter of the nanofiber was investigated. Electrospun nanofibers had a vertical orientation and measurements of the fiber diameters were attained using Scanning Electron Microscopy (SEM). Fiber diameters averaged 172 nm, 243 nm, and 255 nm in graphite concentrations of 0.250 M, 0.375 M, and 0.500 M, respectively. Beaded structures were embedded in the ZnO/graphite composite fiber with averaged diameters of 493 nm, 536 nm, and 283 nm at graphite concentrations of 0.250M, 0.375M, and 0.500M, respectively. With increasing graphite concentration, the electrospun ZnO/graphite composite nanofibers were found to have decreasing bead diameters and increasing fiber diameters. Energy dispersive X-ray (EDX) detected the presence of zinc, oxygen, and carbon (elemental) in the scanned fiber. X-ray diffraction (XRD) pattern showed that peaks of samples were parallel to the standard peaks of ZnO and graphite.
