Abstract
Zinc oxide (ZnO) is a well-known semiconductor material due to its excellent electrical,
mechanical, and unique optical properties. ZnO nanoparticles are widely used for the industrial-scale
manufacture of microelectronic and optoelectronic devices, including metal oxide semiconductor
(MOS) gas sensors, light-emitting diodes, transistors, capacitors, and solar cells. This study proposes
optimization of synthesis parameters of nanosized ZnO by the electrospinning technique. A Box–
Behnken design (BB) has been applied using response surface methodology (RSM) to optimize the
selected electrospinning and sintering conditions. The effects of the applied voltage, tip-to-collector
distance, and annealing temperature on the size of ZnO particles were successfully investigated.
Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images confirm
the formation of polyvinylpyrrolidone-zinc acetate (PVP-ZnAc) fibers and nanostructured ZnO after
annealing. X-ray diffraction (XRD) patterns indicate a pure phase of the hexagonal structure of ZnO
with high crystallinity. Minimal-sized ZnO nanoparticles were synthesized at a constant applied
potential of 16 kV, with a distance between collector and nozzle of 12 cm, flow rate of 1 mL/h, and
calcination temperature of 600 C. The results suggest that nanosized ZnO with precise control of
size and morphology can be fabricated by varying electrospinning conditions, precursor solution
concentration, and sintering temperature.
