Özet

This research aims to investigate the rheological and mechanical properties of drug-loaded nanofibrous surfaces to demonstrate the importance of polymer solution preparation techniques. First, rheological properties of suspension and emulsion PVP/GEL polymer solutions with various concentrations of AZI were determined, including the viscosity, shear stress, loss modulus, complex shear modulus, and storage modulus. Then, nanofiber production was carried out by an emulsion and suspension electrospinning approaches under the optimum process parameters. Finally, the mechanical properties and morphological analysis of all of the nanofibers were determined. The major result of these dynamic rheology studies was that the storage modulus for all the polymer solutions showed the same behavior at low frequency, while they were separated from each other in the high-frequency region. As a result of the mechanical measurements, the low mechanical properties of PVP nanofibers were improved when GEL polymer was added. When comparing the mechanical performance of the emulsion and suspension electrospun nanofibers, it is evident that the suspension electrospun samples have an average of about four times higher tensile strength. The primary finding of this research is that the mechanical properties of nanofibers that consist of the same polymers, the same concentration of polymers, and the same drug content are four times different depending on which production approach is used.
