中文摘要 | gas transport of hydrogen, oxygen, nitrogen, carbon dioxide, and methane in four cardo poly(aryl ether ketone)s containing different alkyl substituents on the phenyl ring has been examined from 30 to 100 degrees c. the permeability, diffusivity, solubility, and their temperature dependency were studied by correlations with gas shape, size, and critical temperature as well as polymeric structural factors including glass transition, secondary transition, cohesive energy density, and free volume. the bulky, stiff cardo and alkyl groups in tetramethyl-substituted tmpek-c resulted in increased h-2 permeability (by 55%) and h-2/n-2 permselectivity (by 106%) relative to bisphenol a polysulfone (psf). moreover, the weak dependence of gas transport on temperature in tmpek-c made it maintain high permselectivities (alpha(h2/n2) in 68.3 and alpha(o2/n2) in 5.71) up to 100 degrees c, exhibiting potential for high-temperature gas separation applications. |
