a Solvent permeation test of 29 nm/XP12 membrane with time and changing the solvents (methanol, acetone, and DMF) under 30 bar pressure in a custom-built cross-flow system. b Change of methanol permeance of 29 nm/XP12 and 35 nm/XP12 membranes with various activation solvent. MeOH, ACT, and ACN represent methanol, acetone, and acetonitrile, respectively. c Various solvent permeances of 29 nm/XP12-D membrane was correlated with the combined solvent property (\({{{{{\delta }}}}}_{{{{{{\bf{p}}}}}}}\)·η−1·\({{{{{d}}}}}_{{{{{{\bf{m}}}}}}}\)−2). 1: ethanol, 2: DMF, 3: acetone, 4: methanol, 5: acetonitrile. d Methanol flux of 29 nm/XP12-D membrane with varying pressures. e DMF flux of 29 nm/XP12 membrane with filtration time. All error bars indicate the standard deviation at two or three measurements.
