Fabrication and physical characterization of Zn (OH) 2/PVA and ZnO nanofibers using Electrospinning nanofiber generator

Zinc oxide nanofibers were prepared using the polymer Zinc acetate solution, by a modest programmable microcontroller aided electro spinning technique. The prepared and calcinated nanofibers were characterized using standard analytical methods. The hexagonal wurtzite structure for calcinated nanofibers of diameters ranging between 10-13 nm were inferred from structural analysis. The Field Emission Scanning Electron Microscope analysis showed that nanofibers sizes are varied from 100 to 500 nm for the prepared and calcinated samples. The optical absorption analysis evidently showed the presence of nanophase Zinc Oxide by means of a strong blue shift (372 nm) in the band edge absorption region. The functional group analysis showed the presence of organic bands related to Polyvinyl Alcohol for uncalcinated nanofiber. This article proposes that an indigenously manufactured electro spinning system can cover the active research area of preparing ceramic and composite nanofiber with various compositions and properties.
