Abstract
In this work the effect of the various nanofillers (modified single wall carbon nanotubes, modified cucurbit[n]urils and bambus[n]urils[1], mesoporous silica) on the permeation and sorption properties of poly(styrene-butadiene-styrene) (SBS) based mixed matrix membranes (MMMs) is presented. SBS as thermoplastic elastomer has high chemical stability, excellent tensile strength and good processability. Transport properties of MMM samples in form of flat films with nanofiller contents up to 60 wt.% were studied at a temperature of 298.15 K. Gas (CO2, O2, N2) and vapour (C1-C4 linear alcohols, water) sorption experiments [2] were performed by a sorption apparatuses equipped with calibrated McBain spiral balances [2,3] with automatic position detection. Gas/vapour permeation was determined by the differential flow permeameter and by fixed-volume pressure increase instrument. From experimental data the appropriate sorption isotherms and transport parameters (permeability, diffusion and sorption coefficients) were determined. The influence of the filler type and concentration on the transport mechanism is discussed.
