dc.description.abstract | Thermally rearranged polymer membranes exhibit extraordinary gas permeability based on a rigid polymer structure with a high free volume element. In this study, TR poly(benzoxazole-co-imide) membranes from 4,4'-hexafluoroisopropylidene diphthalic anhydride (6FDA), 3,3'-dihydroxyl-4-4'-diamino-biphenyl (HAB), 2,2'-bis(3-amino-4-hydroxyphenyl)-hexafluoropropane (bisAPAF), and 2,4,6-trimethyl-m-phenylenediamine (DAM) were prepared to improve their gas separation properties. Copolymer membranes of polyimides and TR polybenzoxazoles may be desirable to generate efficient gas transport properties as well as to process polymers into fiber or film forms. Gas permeability, diffusivity, and solubility of the precursor polyimide and TR poly(benzoxazole-co-imide) membranes were investigated to characterize gas transport properties for small gas molecules including H 2 , O 2 , N 2 , CH 4 , and CO 2 . Thermal rearrangement process resulted in an increase in polymer free volume, which improved the diffusion and sorption coefficients. | en_US |
