Figure 1. (A and B) FESEM images of PP/PE/PP and pore-filing membranes at surface and cross-section, respectively; (C) porosity and percentage of filling of PF-70(IL-EC) membrane; (D) SAXS curves of pore-filling membranes at various IL concentration. EC: Ethylene carbonate; IL: ionic liquid; PFM: pore-filling membrane; PP/PE/PP: polypropylene/polyethylene/polypropylene; SAXS: small angle X-ray scattering.
