The high performance poly(ether-block-amide)(PEBA2533) membrane was prepared by dry phase inversion method, and then used for separation of vanillin from dilute aqueous solutions in the pervaporation-crystallization coupling(PVCC) system. The structural morphology of PEBA2533 membranes were characterized by SEM. The effects of feed concentration and operating temperature on the pervaporation performances of membrane were investigated. The results showed that the swelling degree of PEBA2533 membrane increase...
