Fate of nanoparticles during life cycle of polymer nanocomposites

July 6, 2011
Author(s)
Tinh Nguyen, Bastien T. Pellegrin, Coralie Bernard, Xiaohong Gu, Justin M. Gorham, Paul E. Stutzman, Deborah S. Jacobs, Walter E. Byrd, John W. Hettenhouser, Joannie W. Chin
Nanoparticles are increasingly used in consumer and structural polymeric products to enhance a variety of properties. Under the influences of environmental factors (e.g., ultraviolet, moisture, temperature) and mechanical actions (e.g., scratching

LABORATORY ACCELERATED AND NATURAL WEATHERING OF STYRENE-ETHYLENE-BUTADIENE-STYRENE (SEBS) BLOCK COPOLYMER: ACCELERATION AND CORRELATION

March 23, 2011
Author(s)
Kar T. Tan, Christopher C. White, David J. Benatti, Deborah S. Jacobs, Donald L. Hunston
Indoor accelerated and outdoor field weathering of styrene-ethylene-butadiene-styrene block copolymer have been studied by Fourier transform infrared (FTIR) spectroscopy. In the indoor accelerated experiments, specimens are exposed to ultraviolet-visible

Water based Polyurethane Graphene Oxide Nanocomposites

March 3, 2010
Author(s)
Coralie Bernard, Tinh Nguyen, Bastien T. Pellegrin, Mat Celina, Alexander J. Shapiro, Deborah Jacobs, Kar T. Tan, Sungjin Park, R. S. Ruoff, Joannie W. Chin
Graphene oxides are potentially a new class of nanomaterial to enhance multifunctional properties of polymers because of their remarkable thermal conductivity, mechanical strength, and more importantly, low cost. The graphene oxides, produced by

Studying Long-term Performance of a Nano-ZnO filled Waterborne Polyurethane Coating using Spectroscopies and Microscopies

September 9, 2009
Author(s)
Xiaohong Gu, Dongmei Zhe, Stephanie S. Watson, Guodong Chen, Minhua Zhao, Paul E. Stutzman, Deborah S. Jacobs, Tinh Nguyen, Joannie W. Chin, Jonathan W. Martin
Although inorganic UV absorbers such as zinc oxide (ZnO) and cerium oxide (CeO2) exhibit numerous advantages compared to organic UV absorbers, the mechanisms of how these nanoparticles affect the long-term performance of polymeric coatings are less than

Chemorheological Investigation on the Environmental Susceptibility of Sealants

August 18, 2009
Author(s)
Kar T. Tan, David J. Benatti, Christopher C. White, Donald L. Hunston, Deborah S. Jacobs
One of the major problems with any sealant system is its susceptibility to hostile environments, such as heat, moisture, ultraviolet radiation, oxygen, mechanical stress and biochemical attack. Prolonged exposure to these environments leads to substantial

Linking Accelerated Laboratory Test with Outdoor Performance Results for a Model Epoxy Coating System

October 8, 2008
Author(s)
Xiaohong Gu, Deborah S. Jacobs, Walter E. Byrd, Brian Dickens, Iliana Vaca-Trigo, William Meeker, Tinh Nguyen, Jonathan W. Martin
Laboratory and field exposure results have been successfully linked for a model epoxy coating system. The mathematical model used in making this linkage only assumed that the total effective dosage, additivity law, and reciprocity laws were valid. In this
