Özet
In this study, chitosan and poly(vinyl alcohol) were cross-linked with boron in varying concentrations and chitosan and poly(vinyl alcohol) blend fibers were obtained with electrospinning process. Viscosity and electrical conductivity results revealed that the increase in chitosan and boron content increased the viscosity of the solution and but decreased the electrical conductivity of the fibers. The peaks obtained with FT-IR analyses were in good agreement with literature. SEM micrographs also showed that wavy and curly fibers with relatively small diameters were obtained as the chitosan and boron concentrations were increased. Thermogravimetric data revealed that the formation of a more stable polymer structure as a result of the cross linking with boron.
