Polymers and Complex Fluids Group

Welcome

The Polymers and Complex Fluids Group develops measurement methods, models, data, standards, and science for soft materials, such as multi-phase fluids, gels, and composites, and their constituent components, such as polymeric molecules, nanoparticles, colloids, and fibers. The Group provides expertise in macromolecular measurements, advanced separation methods, processing, rheology, and composite structure needed to define processing, structure and performance relations and accelerate the design of advanced materials.
