Özet
The aim of this study was to prepare polyvinyl borate (PVB)/poly(methyl methacrylate) (PMMA) blend nanofibers by electrospinning process. Polyvinyl borate was synthesized by the condensation reaction of polyvinyl alcohol and boric acid. Since polyvinyl borate itself was not suitable for electrospinning process, polyvinyl borate was blended with poly(methyl methacrylate) prior to electrospinning process. A series of nanofibers with various polyvinyl borate concentrations in poly(methyl methacrylate) were prepared. PVB/PMMA blend nanofibers were characterized by fourier transform infrared spectroscopy (FTER) and scanning electron microscopy (SEM). FTIR analyses showed that boron atoms were found to be integrated into the polymer network. According to SEM images, blending PMMA with PVB decreased the fiber diameter from 218 nm to 93 nm and resulted in appearing the bead structures along the fibers, which increased the surface roughness PVB/PMMA blend nanofiber mats. The water wetting property of PVB/PMMA blend nanofiber mats was influenced by the surface roughness. The contact angle increased with increasing the PVB content of PVB/PMMA blend nanofibers, enhancing the surface roughness. This study also aimed to assess the thermal behavior of PVB/PMMA blends using the thermogravimetric analysis (TGA). The blend composition with the highest polyvinyl borate content was found to be suitable for thermally stable nanofiber formation according to the TGA results.
