Figure shows the water uptake of the IBMA-containing membranes of different compositions as tabulated in Table , varying the sulphonamide monomer between LiMTFSI and LiSTFSI and the crosslinker%. As observed in Figure , a monotonic increase in water uptake is observed as a result of a higher fraction of the hydrophilic sulphonamide monomer [m/n on P(LiM/STFSIm-IBMAn)-2.5%EGDMA],
