posted on 2009-12-08, 11:31 authored by Kevin Terry Cliff, Steve TarletonThis 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.
