摘要：
In this research, novel polybenzoxazine (PBZ) membranes, synthesized from bisphenol-A, formaldehyde and diamines, were coated on a tubular alumina support by dip-coating technique for ethanol purification application via pervaporation. The effects of dipping time and precursor concentration on the membrane preparation and the separation performance showed that both PBZ membranes were remarkably stable, resistant to swelling, and provided an impressively high separation factor of higher than 10,000 for all ethanol concentration ranges, characteristics implying that they could be a good candidate for high purity ethanol production. © W.
