Focus:
Microporous membranes and membrane separations

Research:
The thermally-induced phase separation (TIPS) process is being used to form microporous polymeric membranes for a variety of industrially important applications. Of particular interest are membranes that can withstand high temperatures and harsh chemical environments, and membranes that have narrow pore size distribution. Specific targets are improved membranes for biological separations (such as hemodialysis and virus removal from blood), more robust membranes for industrial process streams, and more efficient separators for lithium ion batteries and NiCd batteries.

Our research on the formation and application of membranes includes fundamental scientific studies and practical technical studies. The fundamental studies provide the scientific understanding necessary to develop the improved membranes that are needed by industry. The technical studies, which are conducted in conjunction with industrial sponsors, put the fundamental knowledge into practice.

The research in this group is enhanced by interactions with Professor Bonnecaze and Freeman of this department, Professor Lawler of our Environmental Engineering Program, and Professor G.G. Lipscomb of the University of Toledo as well as numerous industrial contacts.

Our research group usually averages six to seven people and is funded by a combination of agency and industrial money.
