Confined nanobubbles shape the surface roughness structures of thin film composite polyamide desalination membranes

The ridge-and-valley roughness structure of a polyamide reverse osmosis (RO) membrane has a paramount impact on its separation performance. We show that this surface roughness appearance was shaped by gas nanobubbles confined between the polyamide rejection layer and the substrate. Performing interf...
