摘要
A novel surface sieving membrane was prepared by attaching zeolite crystals on the polymer membrane surface. The top zeolite layer serves as a pre-screen layer which only allows the permeation of small molecules based on a molecular sieving mechanism. The separation factor of the new membrane was substantially increased by 300% for the pervaporation separation of a methanol-dimethyl carbonate mixture.
