Role of Polymer Science in Water Purification Membranes

“Water, water, everywhere, Nor any drop to drink.” As populations increase, finding new, more effective ways to purify existing water sources is becoming more important and innovation with purification membranes through polymer chemistry is leading the way.

Geoffrey M. Geise of the University of Virginia will describe how polymer structure and dynamics influence the movement of water and salts through separation membranes. Abhishek Roy of the National Renewable Energy Laboratory will share the importance of polymer science in understanding polyamide based reverse osmosis membranes and how new polymer characterization methods lead to fundamental breakthroughs in correlating polymer structure with predicting properties in purification membranes.

This ACS Webinar will be moderated by Syed Islam of Oak Ridge National Laboratory, and co-produced with the ACS Division of Polymer Chemistry.

What You Will Learn
