Material Measurement Laboratory /Materials Science and Engineering Division

Polymers Processing Group

The Polymers Processing Group studies the processing and characterization of materials at dimensions where internal and external interfaces substantially impact their properties, with the intent of advancing measurement science, standards, and technology needed by U.S. industry.

Group Scope

Polymers are processed into films and other useful shapes through liquid → solid transitions. The structure that forms is always non-equilibrium and the processing parameter space is typically vast. We develop measurements to characterize the structure that forms during polymer processing, and to characterize how that structure forms. By applying these approaches, we aim to accelerate materials development and process development across applications including microelectronics, biosensing, and structural materials.
