Abstract
Two different directions for further research emerged from the studies conducted: increasing the time the fibres stay in the first spinning bath; this should lead to the creation of a higher quality surface layer and greater selectivity of pervaporation; continuing research on the creation of composite membranes; creating symmetric porous hollow-fibre membranes as substrate and applying a thin layer of PDMS on them to ensure selectivity of the membranes could be best here.
