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
There is always a degree of uncertainty surrounding measurements of polymeric materials, especially complex mixtures with varying distributions in chemistry
The purpose of this project is to create rheological measurement methods and tools, focused on using minimal fluid volumes, to measure local flow dynamics and
The goal of the Particles, Tubes and Colloids (PTC) project is to develop measurement methods and technologies to enable and improve commerce of dispersed
The Polymer Analytics project was established with the goal of accelerating the discovery of new polymer physics through the development of datasets, methods
