CNT-polyamide nanocomposite membranes for gas and water separations

, , , , , , , , , ,
We have developed asymmetric carbon nanotube/polyamide membranes for desalination applications. The carbon nanotubes are functionalized with zwitterionic groups that control the rejection of anionic species, while permitting the transport of water. Water flux measurements demonstrate [...]

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 [...]
