Sažetak
The influence of experimental conditions on the formation of ZnO fibers by electrospinning has been investigated. The electrospinning of a viscous suspension containing polyvinylpyrrolidone and zinc acetate in C2H5OH/H2O produced very long fibers (several hundred μm). Upon calcination a thin deposit of precursor fibers at 400 or 500 °C for 1 h the fibers consisting of ZnO nanoparticles were obtained. On the other hand, ZnO fibers were not obtained upon heating a thick deposit of precursor fibers at 600 °C for 6 h. At all three heating temperatures (400, 500 or 600 °C) ZnO nanoparticles with a gradual increase in size were produced. The Raman spectrum of ZnO nanoparticles formed at 600 °C showed additional bands which were assigned to graphene oxide. It was suggested that in the thick deposit the organic com¬ponent did not burn out completely, i.e., the residual carbon (graphite) transformed into graphene oxide for the experimental conditions applied.
