Preparation of High Molecular Weight Poly(Vinyl Carbazole) Web by Electrospinning
High molecular weight poly(N-vinyl carbazole) (PVCz) nanowebs were prepared by electrospinning technique. To investigate the effects of type of solvents on the spinnability and the morphology of electrospun PVCz, PVCz solutions were prepared by dissolving PVCz in chloroform and 1,1,2,2-tetrachloroethane (TCE) and were spun at various electrospinning conditions. The spinnability of PVCz in TCE was better than those in THF and in chloroform, which was ascribed to the difference in solution properties. Bead-fiber morphology was observed when the concentration was low concentration, but fine fibers were obtained when the concentration was high concentration.
