Structural and transport properties of polydimethylsiloxane based polyurethane/silica particles mixed matrix membranes for gas separation

다국어 초록 (Multilingual Abstract)

Mixed matrix membranes of synthesized polyurethane (PU) based on toluene diisocyanate (TDI), polydimethylsiloxane(PDMS) and polytetramethylene glycol (PTMG) with polyvinyl alcohol based polar silica particles wereprepared by solution casting technique. The homogeneity and thermal properties of the prepared PDMS-PU/silica membraneswere characterized using scanning electron microscope (SEM), differential scanning calorimetry (DSC) andthermal gravimetric analysis (TGA). The SEM micrographs confirmed the distribution of silica particles in the polymermatrix without agglomerations. Gas permeation properties of membranes with different silica contents were studiedfor pure CO2, CH4, O2, He and N2 gases. The obtained results indicated the permeability of the condensable and polarCO2 gas was enhanced whereas permeability of other gases decreased upon increasing the silica content of the mixedmatrix membranes. The permeability of CO2 and its selectivity over N2 was increased from 68.4 Barrer and 22 in purePDMS-PU to 96.7 Barrer and 64.4 in the mixed matrix membranes containing 10 wt% of the silica particles.
