Abstract
The introduction of inorganic nanomaterials as additives into polymers has resulted in polymer nanocomposites exhibiting a multiplicity of high-performance characteristics beyond what traditional polymeric composites possess. These “multifunctional” features attributable to polymer nanocomposites consist of improved properties, such as thermal, flame, ablation, electrical, moisture, chemical, permeability, and others. 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 seminar includes: an overview of different nanomaterials, processing techniques, and selective examples to examine the behavior of polymer nanocomposites for applications, such as re-entry vehicles, rocket engines, additive manufacturing, and fire protection.
