Abstract

The production of polymer nanocomposites with excellent dispersion of nanofillers has proven to be a major challenge using conventional polymer processing methods. As a result of commonly poor dispersion of nanofillers, the promise of enhanced properties in nanocomposites has often gone unrealized. We have recently demonstrated that a process called solid-state shear pulverization (SSSP) can yield well-exfoliated polymer-clay nanocomposites and well-dispersed polymer-multiwall carbon nanotube and polymer-alumina nanoparticle composites. Furthermore, the exfoliation of dispersion achieved via SSSP is stable during subsequent melt processing of the nanocomposites made via SSSP. The connection between synergistic macroscopic properties, from modulus to thermal stability to conductivity, and dispersion of nanofiller is illustrated by the results obtained in this study.
