摘要:
Permeability, diffusivity and solubility of gases in polymer/inorganic composite membranes are reported. Membranes were prepared by covering a porous Vycor glass tube with polysilastyrene solution followed by pyrolysis at 382 and 470-degrees-C. The experimental data indicate that the gas separation properties of such a membrane are a combination of the transport characteristics of the polymer and the molecular-sieve material. Selectivity factor for H-2/SF6 increases to 328 for the membrane pyrolyzed at 470-degrees-C whereas for the unpyrolyzed polymer it is merely 10.
