Scott Mauger is a scientist in the Process Science and Engineering Group within the Chemistry and Nanoscience Center. His research focuses on the science and engineering of roll-to-roll coating processes for manufacturing. Most of this work focuses on fuel cells and electrolyzers including work as part of the U.S. Department of Energy (DOE) Hydrogen and Fuel Cell Technologies Office’s Million Mile Fuel Cell Truck (M2FCT) and H2NEW consortia. This includes researching how coating and drying physics impact the structures and functional properties of roll-to-roll coated layers. Another aspect of his research uses rheology and other techniques to understand colloidal interactions within particle/polymer dispersions to design dispersions for coating processes.

Additionally, he leads tasks studying multilayer coating and mixing processes within the DOE's Advanced Manufacturing and Industrial Decarbonization Offices' Advanced Materials Manufacturing Roll-to-Roll Multilab Collaboration. Other projects have included research developing coating processes for batteries and polymer films.
