Details of Surface Features in Aromatic Polyamide Reverse Osmosis Membranes Characterized by Scanning Electron and Atomic Force Microscopy
TL;DR: In this paper, the surface roughness and surface area were mainly affected by the existence or nonexistence of the crosslinking and free amide groups not pertinent to the formation of the hydrogen bonding, which in turn contributed to the water permeability.

Influence of the diamine structure on the nanofiltration performance, surface morphology and surface charge of the composite polyamide membranes
TL;DR: In this paper, different thin films were prepared with small structural differences to help understand how the amines structure influences the membranes nanofiltration performance, surface charge and morphology, and the average water permeability of the samples was correlated with hydrophobic/hydrophilic character of the monomers by use of the octanol-water partition coefficient.
