Interactions of Polymers with Fillers and Nanocomposites, NIST, June 18-19, 1998: A Workshop Report



Alamgir Karim


Control of molecular-level interactions and measurement of polymer dynamics at the filler interface were identified by participants at a recent NIST sponsored workshop as the most critical issues in filled polymers and nanocomposites. Although filled polymers already represent a substantial fraction of polymer materials, recent developments in nanocomposites have attracted renewed interest in developing the science and technology base to optimize performance. The workshop focused on identifying the most critical issues hindering improvements in applications of filled polymers and nanocomposites. Of the 75 external participants, 50 were from industry, mostly experts in the area of filled polymer technology. Through productive discussions, the workshop participants highlighted and prioritized a range of future research and measurement needs for filled materials. The discussions also laid the foundation for future research in this area, and collaborations between NIST, industry and academia. The Polymer Blends and Processing Group of the Polymers Division, MSEL initiated research on polymer-filled interactions last year, using X-ray, neutron and light scattering in combination with microscopy techniques, and concepts that had been previously applied with great success on polymer blends. The results of the workshop will be used to plan future directions of the NIST work.
