31. X-ray diffraction (XRD) was not successful due to the apparent random alignment of pores themselves and the detection limit of XRD for an ordered ultrathin polymer layer.
32. This observation might be attributed to interference from the movable hydrophilic side chains of RSA adsorbates on the membrane surface.
33. 2 scans were found to be most appropriate for RSAMs to avoid scratches, dents, and contaminants introduced during the membrane fabrication process.

35. High-resolution XPS study on the S 2p content (relative to the C 1s content) of the membrane external surface ( < 10 nm) did not provide evidence for a thin-layer surface model with significantly reduced or no S 2p signal. In this case, if a thin layer exists, the XPS signals are beyond the detection limit due to the loose packing of the RSAs.
