As subclass of Metal organic framework-materials) zeolitic imidazolate frameworks (ZIFs) have exhibited great potential for,numerous applications because of their special three-dimensional structure. Up to now, utilizing ZIP membranes for liquid separations is still limited because it is very difficult to select suitable materials and to fabricate integrated membranes. In this work, a modified contra-diffusion method was carried out to prepare ZIF-71 hollow fiber membranes. The Metals Zn2+ and the organic links imidazole would meet and react on the interface of ceramic hollow fiber through diffusion. The as-prepared ZIF-71 membrane exhibits good performance in separation of ethanol water mixtures.
