Zwitterionic Polymers for Fouling-Resistant Desalination Membranes
Zwitterionic copolymers for desalination membranes Background Approximately 97% of the earths water is undrinkable; of the remaining water only 1% is easily accessible. Unfortunately, current methods of sea water desalination are costly and inefficient. Polymeric membranes are a promising solution to this problem and have received significant focus...

Charge mosaic membranes for desalination of brackish water
Project #D2019-22Background Reverse osmosis is a common technique used in desalination; it utilizes high pressure to separate water from salt. Although this separation technique is widely used for desalination, it would be advantageous to use a membrane that allows for selective transport of salt relative to water. Charge mosaic (CM) membranes...
