Abstract: Using polysulfone (PSF) hollow fiber membrane as the supported membrane, dibenzoyl-L-tartaric Acid (L-DBTA) as a template, methyl methacrylate (MMA) as functional monomer and glycol dimethyacrylate (GDMA) as a cross-linker chiral (L-DBTA), molecular imprinted hollow fiber composite membrane (CMIHFCM) was fabricated by surface thermal-polymerization method. Effect of surface thermal-polymerization process on pervaporation performance was obvious. The pervaporation properties of CMIHFCM for the separation of ethanol/water solution was studied. The pervaporation results show that at 40ŚC 20% ethanol in the ethanol/water solution, the separation factor is 1086 while permeation flux is 2093 g/m2 h; 50% ethanol in the ethanol/water solution, the separation factor is 2181 while permeation flux is 2185 g/m2 h. Besides, the apparent activation energy of pervaporation of CMIHFCM is 16.9 kJ/mol
