Non-stoichoimetric crystalline ZIF-62 was used as the filler for a 6FDA-DAM polyimide-based composite membrane. In situ melting and vitrification of ZIF-62 was then performed, to yield the ZIF-62 glass phase (agZIF-62), within the polymer matrix. Focus ion beam scanning electron microscopy (FIB-SEM), thermal characterisation and membrane separation tests demonstrate the filling of voids at the MOF/polymer interface from the liquid phase of ZIF-62.
非化学计量比的晶体ZIF-62被用作基于6FDA-DAM聚酰亚胺的复合膜的填料。然后对ZIF-62进行原位熔融和玻璃化处理，以在聚合物基质中生成ZIF-62玻璃相（agZIF-62）。聚焦离子束扫描电子显微镜（FIB-SEM）、热表征和膜分离测试表明，ZIF-62液相填充了MOF/聚合物界面处的空隙。
