Fig. 5: Water vapor permeation performance.

a Adsorption and b diffusion in pure PEBAX, PEBAX/F-Ce-4%, and PEBAX/IL@F-Ce-4% membrane at different water vapor activities. The water vapor permeability and H2O/N2 selectivity of the (c) PEBAX/F-Ce MMMs and PEBAX/IL@F-Ce MMMs, d Nafion/IL@F-Ce MMMs and SPEEK/IL@F-Ce MMMs. e The water vapor flux of pure PEBAX membrane, PEBAX/F-Ce-4% membrane, and PEBAX/IL@F-Ce-4% membrane. f The effect of the pore diameter of nanosheets on water vapor permeability and selectivity of the MMMs. All error bars represent the standard deviation for at least five independent measurements.
