Effect of emimBF4 ionic liquid concentration on ionic liquid-polymeric membrane (ILPM) for CO2/CH4 separation

In the current study, polyethersulfone based (emim)bf4 ionic liquid polymeric membranes (ILPMs) were synthesised for CO2 separation from CH4. Two weight percentages (10% and 20%) of (emim)bf4 ionic liquid was added in the prepared doped solution; flat sheet dense membranes were synthesised by the dr...
