Myoungbae Lee, a postdoc at the Virginia Tech Department of Chemical Engineering (Jim McGrath's group), was recently at Giner to work with some of our specialized membrane characterization equipment. He made a presentation for us while he was here at one of our periodic Pizza Seminars, which expanded on Effects of block length and solution-casting conditions on the final morphology and properties of disulfonated poly(arylene ether sulfone) multiblock copolymer films for proton exchange membranes.
We got to hear some of his latest results concerning details of his work with us on a DOE Fuel Cell project. The VT multiblock copolymer materials are a potential future source of low-cost proton exchange membrane (PEM). Though specifically addressing the effect of various (thermal and other) treatments on the properties of the VT membranes, it helped give us insight into other PEMs, including Nafion (today's baseline fuel cell membrane).
