Hybrid membranes of metal–organic molecule nanocages for aromatic/aliphatic hydrocarbon separation by pervaporation

Abstract

Hybrid membranes composed of porous metal–organic molecule nanocages as fillers embedded in a hyperbranched polymer (Boltorn W3000) were fabricated, which exhibit excellent pervaporation separation performances towards aromatic/aliphatic hydrocarbons. The unique nature of the molecule-based fillers and their good dispersion and compatibility in/with the polymer are responsible for the good membrane properties.
