【 摘 要 】

In this study aloe vera liquid extract was added to PVA to obtain nanofiber mats with integrated bioactive compounds. Nanofibers are effective in drug release process and the most cost and time effective way to produce them is through roller electrospinning method. Several concentrations of PVA and aloe vera extract have been prepared, as well as pure 10 wt% polyvinyl alcohol solution to compare their properties. Viscosity and electroconductivity of solutions were measured, atomic force microscopy was used for evaluation of nanofiber mats morphology and diameter measurements, samples were analysed and compared by Fourier transform infrared spectroscopy and mechanical properties of the nanofiber mats were tested.
