Material Measurement Laboratory /Materials Science and Engineering Division

Polymers and Complex Fluids Group

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

Projects and Programs

Macromolecular Architectures

Ongoing
This project’s purpose is to synthesize and characterize model thermoplastics, thermoplastic elastomers (TPE), and mixed resins with systematic variation of polymer sequence, chemistry, and architectures to generate libraries of quantitative structure-property relationships validated by multiple

Fluid Suspensions and Emulsions

Ongoing
We aim to: Develop measurement capabilities to relate solution structure and viscosity through novel combinations of unique small volume, high shear rate rheometers with scattering and particle-imaging techniques. A major application of these capabilities is understanding self-association in fluids

Particles, Tubes, and Colloids

Ongoing
Description A highlight of the PTC project is our success in purification of well-defined SWCNT populations using liquid phase separation methods. Although we use multiple techniques and methods, ion exchange chromatography, rate-zonal and isopycnic ultracentrifugation, size exclusion chromatography

Polymer Analytics

Ongoing
This project focuses on a variety of activities to achieve the aforementioned goal of accelerating the discovery of new polymer physics. Polymer databases In collaboration with partners, we build FAIR (findable, accessible, interoperable, reproducible) data resources that enable machine learning
