Polymer Membrane Research at UVA
The Geise research group seeks to develop structure/property/processing relationships to guide polymeric materials design for membrane-based liquid separation and energy applications by understanding the influence of nano- and molecular-scale interactions and phenomena on mass transfer and system-level performance.
We are based in the Department of Chemical Engineering at the University of Virginia.
Geise Group Research:
Water-Energy Nexus
Our research focuses on experimental studies aimed at solving fundamental and practical problems related to water and ion transport through polymers that could be used as membranes in a variety of water and energy applications. Providing sustainable and economic supplies of purified water and clean energy solutions is a critical global challenge for the future, and polymer membranes will play a key role in these efforts.
We seek to rationally tailor and design polymers at the molecular level and process those polymers to engineer advanced membrane materials that will expand access to clean water and enhance the use of renewable energy sources.
Water Purification for a Thirsty World
Within the next 10 years, the United Nations predicts that nearly two-thirds of the world’s population may find themselves living in a water stressed area.
Today, the vast majority of desalination processes are performed using polymer-based membranes. Improved membranes are needed to meet the challenges of economically and sustainably purifying increasingly saline and contaminated water sources around the globe.
Clean and Renewable Energy
to Light our Future
Energy demand around the globe is projected to increase by more than 50% over the next 35 years, and sustainable, low-carbon footprint energy resources are needed to meet this increasing energy demand.
Technologies such as large-scale flow batteries, reverse electrodialysis, and capacitive mixing rely on polymer membranes to regulate ion transport. Improved membrane selectivity will enable advances in renewable energy storage and generation technologies.
