Figure 3

FE-SEM images of PMIA membranes prepared from solutions with different DTAB concentrations of (a) 0.05, (b) 0.1, (c) 0.15, and (d) 0.2 wt% at RH of 25%. (e) Filtration efficiency and pressure drop, (f) quality factor, and (g) pore size distribution of PMIA NF/N membranes (~0.125 g m−2) with different DTAB concentrations.
