摘要：Metal-organic framework (MOF) crystals of Cu3(BTC)2 with a high surface area (1396 m2·g-1) were synthesized and mixed with polyimide (PI) to prepare mixed-matrix membranes (MMMs) for gas separations. The PI-Cu3(BTC)2 blend was successfully spun into MMM hollow fiber by the dry/wet-spinning method. SEM images of the fiber cross sections revealed significant plastic deformation of the polymer matrix owing to the strong affinity between Cu3(BTC) 2 and PI. The H2 permeance and the selectivity of H 2 with respect to other gases such as N2, CO2, O2, and CH4 both increased markedly with increased Cu 3(BTC)2 loading. At a loading of 6 wt % Cu 3(BTC)2, the permeance of H2 increased by 45%, and the ideal selectivity increased by a factor of 2-3 compared to the corresponding values for pure PI. ? 2010 American Chemical Society.
