| Abstract: | The hydrophilicities of a series of blend modified polyimide membranes and the apparent viscosities of mixed solutions were investigated.The results show that both membrane hydrophilicities and solution(viscosities) were increased with increasing the quantity of quaternary ammonium salt(BAN) in the solution,and a viscosity enhancement phenomenon was observed.The dehydration properties of the blend hollow fiber membranes were tested,it was found that the increases of the pressure and the sweeping flux favored the dehydration performances of the blend membranes.Although the properties of membranes are not always improved with increasing the membrane hydrophilicity,when the quantity of quaternary ammonium salt(BAN) is appropriately increased,the dehydration properties of blend hollow fiber membranes would be improved effectively. |
