dc.description.abstract |
Inspired by the bio-adhesive ability of the marine mussel, highly hydrogen permselective ZIF-8 membranes were prepared on polydopamine functionalized stainless-steel-nets (SSNs). With polydopamine functionalization of SSNs under mild conditions, the nucleation and growth of well-intergrown ZIF-8 membranes were promoted through the formation of strong non-covalent and covalent bonds, which was helpful to enhance the membrane's separation selectivity while maintaining high permeance. For binary mixtures at 100 degrees C and 1 bar, the mixture separation factors of H-2-CO2, H-2-N-2, H-2-CH4 and H-2-C3H8, were found to be 8.1, 15.0, 23.2 and 329.7, which by far exceed the corresponding Knudsen coefficients and those of the as-reported ZIF-8 membranes. The ZIF-8 membranes also displayed high permeances, with the H-2 permeance higher than 2.1 x 10(-5) mol m(-2) s(-1) Pa-1 due to the high void volume of the SSNs. |
