SEM images and pore size distribution of different concentrations of CA and PVDF-HFP spin-coated membranes. (a) SEM image of 15 wt% CA and its corresponding magnified image; (b) SEM image of 17.5 wt% CA and its corresponding magnified image; (c) SEM image of 20 wt% CA and its corresponding magnified image; (d) 15 wt%, 17.5 wt%, and 20 wt% CA pore size distribution; (e) SEM image of 12 wt% PVDF-HFP and its corresponding magnified image; (f) SEM image of 16 wt% PVDF-HFP and its corresponding magnified image; (g) SEM image of 20 wt% PVDF-HFP and its corresponding magnified image; (h) 12 wt%, 16 wt%, and 20 wt% PVDF-HFP pore size distribution. The yellow marks indicate the enlarged view of the morphology.
