摘要：

A blend membrane consisting of 5.3 wt% copoly(N-isopropylacrylamide/1H,1H,2H,2H-perfluorododecyl acrylate) and poly(dimethylsiloxane) showed a high ethanol permselectivity (alpha(EtOH) = 19.7 at 24-degrees-C) in pervaporation of 2.5 wt% aqueous ethanol solution. The value of alpha(EtOH) had a maximum at about 36-degrees-C. This behaviour was due to the water repellency and thermal transition of the copolymer accumulated at the membrane surface.
