Enhanced RO Performance of Polyamide Bi-layer Membranes Prepared by Sequential Interfacial Polymerization

, , , , , , , , , ,
We have developed polyamide bi-layer thin film composite membranes to enhance RO-desalination performance. The polyamide bi-lyer membrane consists of conventional non-substituted aromatic polyamide under-layer and HFA-substituted aromatic polyamide top-layer, which can be esaily prepared by [...]
