**Abstract**
 To prepare fine and even poly(N-vinyl carbazole) (PVCz)/polystyrene (PS) blend webs, we performed a series of experiments varying processing parameters, including the type of solvent, PVCz/PS blend ratio, applied voltage, and tip to the collector distance (TCD). It was found that the morphology and the average diameter of PVCz/ PS blend web were strongly correlated with electrospinning conditions. The morphologies of PVCz/PS blend webs were beaded or fine fibre structures, depending on the blend ratio of PVCz and PS. Increasing content of PS in the spinning solution tended to produce higher spinnability and the average diameter of electrospun web became smaller. The average diameter of the PVCz/PS blend web was slightly decreased with increasing applied voltage. In the case of TCDs, there was no significant effect on the PVCz/PS blend web morphologies but on increasing the TCD, the average diameter of the PVCz/PS blend webs slightly decreased. 15 Refs.
