a The velocity distribution of Omim+, Cl−, and H2O confined within PDMS walls under pressure gradient of 0.084 atm/nm. b The enhance factor for ILs with x(H2O) = 4 and 13 as a function of the pressure gradient. c The charge distribution as a function of distance between the two PDMS layers when x(H2O) is 0 (bottom), 4 (middle), and 13 (top).
