Analysis of the optical properties of PVP/ZNO composite nanofibers

Abstract

The aim of this study was to produce nanocomposites polymer fibers, with the participation of the reinforcing phase in the form of ZnO nanoparticles with a matrix of polyvinylpyrrolidone (PVP), made by electrospinning. Furthermore, examining the impact of the concentration of reinforcing phase on the optical properties of the obtained composites nanofibers. The morphology of nanofibers was examined by atomic force microscope and it showed that the applied process parameters gave the polymer fiber mats PVP from 10 % solution PVP/EtOH and composites PVP/ZnO from 10 % solution, wherein the concentration by weight of the used reinforcing phase was as follow: 5 and 10 %. To improve the influence of the concentration by weight of the used reinforcing phase on the optical properties, the spectroscopy UV-Vis has been used.
