METHODOLOGICAL INFORMATION
--------------------------

Field-emission scanning electron microscopy (FE-SEM, S-4800, Hitachi) was used to characterize membrane surface morphology.
Transmission electron microscopy (TEM, CM100, Philips) was used to resolve membrane cross-section structure.
Atomic force microscopy (AFM, MFP-3D, Asylum Research) was used to determine membrane surface roughness.
X-ray photoelectron spectroscopy (XPS, Thermo Fishier Scientific) was employed to analyze the elemental composition of membrane surface.
ζ potential analyzer (EKA, SurPASS 3, Anton Paar) were applied to measure membrane surface charge.
Attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR, Nicolet iS5, Thermo Fisher Scientific) was used to scan functional groups on membrane surface.
Gas chromatograph (GC, Trace 1310, Thermo Fisher).
