영문 초록

In this study, adapting high molecular weight PVCz and controlling three major parameters for electrospinning, we successfully prepared novel PVCz fibrous webs. SEM images showed that the structure and morphology of electrospun PVCz webs depended on processing parameters such as solution viscosity(e.g. concentration and polymer molecular weight), AV, TCD, and the type of solvent. Concentration of poly(N-vinyl carbazole) (PVCz) solution was varied from 3 to 18 wt(%). All electrospinning procedures were carried out at 25 °C room temperature. Applied voltage was ranged from 15 to 30 kV. Tip-to-collector distance(TCD) was varied from 10 to 40cm. In the cases of, using chloroform as a solvent, the fiber diameters in the range from 3.8/mi to ll.Qum were obtained by varying the solution concentration. It was found that the morphology of electrospun PVCz web was strongly correlated with viscosity. At lower solution concentration，webs containing beads and beads-ont으fibers were prepared, while, at higher one, fine and uniform fibers in webs could be formed. Average diameters of fibers in webs were decreased with increases in the applied voltage and TCD.
