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.
Additive manufacturing (AM) is a high-priority technology growth area for U.S. manufacturers. Innovative AM processes that fabricate parts layer-by-layer
For all the promise they have shown in the lab, polymer solar cells still need to “get on a roll” like the ones employed in printing newspapers so that large
An innovative three-in-one instrument that allows scientists to correlate the flowability of soft “gooey” materials such as gels, molten polymers and biological
Our goal is to develop measurements that quantify the shape, size, orientation, and fidelity of nanoscale patterns as a platform to quantitatively evaluate
This project is focused on the measurements needed to accelerate the innovation cycle for semiconducting-inks for sheet-to-sheet and roll-to-roll printing, to
Additive manufacturing (AM) is a process for fabricating parts directly from 3-D digital models which has tremendous potential for producing high-value, complex
The rheology of polymer crystallization is an old problem that often defies explanation due to the complex interrelationships between crystallization and flow
