Seminar - Fundamentals, Properties, and Applications of Polymer Nanocomposites by Prof. Joseph H. Koo
Date:04 Oct 2019 ( Friday)
Time:11:00 am – 12:00 pm
Venue:EF305

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 mechanical, thermal, flammability, ablation, electrical, chemical, permeability, optical, 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 introduction to nanotechnology, an overview of different nanomaterials, processing and characterization techniques, and selective examples to examine the behavior of polymer nanocomposites for additive manufacturing, re-entry vehicles, rocket propulsion engines, and fire protection.
