We have determined the gas transport properties of He, H2, O2, N2, and CO2 for 6FDA-durene homopolymer and 6FDA-durene/pPDA copolyimides. The 6FDA-durene exhibits the highest permeability with the lowest selectivity. Permeability of copolymers decreases with increasing 6FDA–pPDA content, while ...
The physical and gas transport properties of homo-polyimides, 6FDA-durene and 6FDA-2, 6-diaminotoluene (2,6-DAT), and their copolyimides, 6FDA-durene/2,6-DAT with different diamine ratios, were characterized. The glass transition temperatures of the copolyimides obtained from DSC experiments wer...
Polymer blendswith different polynorbornene/6FDA-durene ratios were prepared. • The prepared membranes exhibit excellent H2permeation andpermselectivity. • The addition of 6FDA-durene improves thethermal stabilityof the blend membranes. Abstract ...
