    Eletcrospinning method can be used in preparation of sub-micron and nanosized fibres. The main commercial application of electrospun materials is aerosol filtration, but they can also be used in various other application including medical and water filtration membranes. Cellulose acetate (CA) is widely used in membrane applications. CA is soluble to acetone, which evaporates very fast in electrospinning process and thus is difficult to be used in materials preparation due to nozzle blocking. In this presentation we will study improving electrospinnability of CA by reduce nozzle blocking tendency. This was carried out, firstly, using solvent mixtures containing also solvent with higher boiling point, and secondly, by using excess solvent feed onto tip of the nozzle. In addition to evalution of these methods we also present premilinary results concerning use of these fibres in membrane applications.
