The fluorinated polyamide showed higher permeation and lower separation for PV of water/eth-anol solution (e.g., a separation factor of 36 and a permeation rate of 383gm 2h-i when the concentration of ethanol in the feed was 90wt% and the feed temperature was maintained at 25 °C) in comparison to the nonfluorinated analog (a separation factor of 60 and a permeation rate of 293gm 2h i) under the same conditions. This was due to the bulky...
