dc.description.abstract | A comprehensive and fundamental gas transport study of ladder-structured polysilsesquioxanes(LPSQs) was systematically performed by investigating the effects of various alkyl substituents, different copolymer ratios, and UV-irradiation induced photo-crosslinking on gas separations. Overall, LPSQ membranes are more suitable for CO2/N-2 and CO2/H-2 separations due to are latively high affinity towards CO2 as well as rubbery polymer properties. The gas transportin LPSQ membranes was well interpreted by two important parameters, the inter-chain distance and the side chain mobility. A combination of larger inter-chain distance and higher side chain rigidity tends to increase the fractional free volume, resulting in higher gas permeability. Also, it was successfully demonstrated that the separation performance of LPSQ membranes can be predicted by using alogarithmic permeability relationship based on the transport characterization for a series of ladder-structured poly(phenyl-co-methacryloxypropyl)silsesquioxanes. Lastly, the UV-curing process reduced the permeability of LPSQ membranes, increasing the selectivity due to the restricted chain mobility. | - |
