Reverse osmosis and nanofiltration membranes commonly adopt a thin film composite (TFC) structure featuring a polyamide rejection layer formed on a porous substrate. Recent studies have shown compelling evidence that the separation performance of TFC membranes is critically influenced by their substrates. ...
polyamide TFC membranes in the drying process, acid/alkali solution, high temperature and active chlorine solution, and then the strategy of corresponding stability improvement is summarized. By systematically combing the latest research progress of four kinds of “special stable” TFC desalting membranes...

It was reported that polyamide RO membranes are rough due to the ridge and valley presence in their structure. The surface roughness of the PA and PA-g-P(t-BA) membranes was found to be 40 μm and 46 μm, respectively. The increase in surface roughness of the PA-g-P(t-BA) ...
TFC membranes are composed of a polyamide (PA) selective layer on the porous substrate, and the overall permeability, selectivity and solute rejection of the TFC membranes are mainly determined by the active PA layer. Although TFC membranes have been well received in industry, membrane scientists ...
