—All Welcome—


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 behaviour of polymer nanocomposites for additive manufacturing, re-entry vehicles, and rocket propulsion engines.


Dr. Koo has over 40 years of industrial and academic experience in program and engineering management.  He is Senior Research Scientist/Research Professor/Director of Polymer Nanocomposite Technology Lab in the Department of Mechanical Engineering at The University of Texas at Austin, Austin, TX.  Dr. Koo is the founder of KAI, LLC and currently serves as Vice President and CTO.  He is a SAMPE Fellow and Chairman of the SAMPE Nanotechnology Committee.  Dr. Koo is an Associate Fellow of AIAA and Past-Chair of the AIAA Materials Technical Committee.  He serves on the advisory board of the U.S. National Space and Missile Materials Symposium.  He is the Editor-in-Chief of Flame Retardancy and Thermal Stability of Materials.  He specializes in polymer nanocomposites: processing, characterization, and applications, such as ablatives for thermal protection systems, flame-retardant polymers, additive manufacturing, fire resistant fabrics & textiles, thermally conductive polymer matrix composites, sensor to measure in-situ ablation recession and thermal properties, sensors to measure char strength, thermophysical properties characterization, material response ablation modeling, modeling of polymer degradation, and insensitive munitions technology of solid rocket motors. Dr. Koo’s publications include 3 books, 14 book chapters, and over 550 papers/presentations/patents in materials, thermal, and optical science disciplines.
