Dr. Freeman’s Web site
Dr. Freeman researches the relationship between polymer structure, processing and properties. He studies the effect of polymer structure and superstructure on the solubility, diffusivity, and permeability of small molecules in polymers and polymer-based materials. His research seeks to understand the effect of chemical composition and polymer structure on polymer properties. This research has applications in controlled drug delivery devices and techniques and barrier plastics for food and specialty packaging. Recently, his lab designed a membrane material that can separate hydrogen from carbon dioxide and other contaminant gases. The membrane can purify hydrogen efficiently in its most usable form for fuel cells and oil refining.
Research interests:
- Gas separation materials
- Gas-vapor barrier materials
- Membranes for water purification
- Membrane module modeling
