Colloquium Date: Monday, May 10, 2010
A bi-weekly event to present and discuss issues related to developments, applications and commercialization of nanotechnology.
“Polymer Nanocomposites with Mulifunctionality Designed for Extreme Environments ”
Joseph H. Koo, Sc.D
The University of Texas at Austin
(VIDEO CONFERENCED FROM AUSTIN, TX)
The introduction of inorganic nanomaterials as additives into polymers has resulted in
polymer nanostructured materials exhibiting a multiplicity of high-performance characteristics
beyond what traditional polymeric composites possess. These "multifunctional" features attributable
to polymer nanocomposites consist of improved thermal stability, flame properties, ablation resistance,
moisture & chemical resistance, decreased permeability, charge dissipation, thermal&electrical conductivity.
Through control/alteration of the additive at the nanoscale level, one is able to maximize property
enhancement of selected polymer systems to meet or exceed the requirements of current commercial,
military, and aerospace applications. This talk includes: a brief overview of different nanostructures
and studies of polymer nanocomposites behavior when exposed to hostile rocket propulsion and fire environments.
