Abstract: This paper details the characterisation (e.g. stiffness, swelling) of catalyst crosslinked polydimthylsiloxane (PDMS) and its subsequent performance as the selective layer in polyacylonitrile (PAN)/PDMS composite nanofiltration membranes. The latter is illustrated by way of the representative filtration performance of 9,10-diphenylanthracene solute from n-heptane solvent. It was found that altering the composition of the PDMS polymer has a relatively large effect on the rigidity of the material but little effect on the extent of solvent induced swelling. Additionally, when used as part of a membrane, increasing the catalyst amount has the dual effect of increasing solute rejection and lowering solvent flux. In this way a modicum of tailoring can be introduced to the membrane manufacture process to suit specific process needs.
