Revealing the Interphase in Polymer Nanocomposites

March 16, 2011
Author(s)
Mauro Zammarano, Paul H. Maupin, Li Piin Sung, Jeffrey W. Gilman, Douglas M. Fox
Morphological characterization of polymer nanocomposites is a fundamental challenge that is complicated by multiple length scales. Here, we report a technique for high-throughput monitoring of interphase and dispersion in polymer nanocomposites based on

Long-Term Performance of Nano-Filled Polymeric Materials: Effect of ZnO Nanoparticles on Photodegradation of a Waterborne Polyurethane Coating

July 8, 2009
Author(s)
Xiaohong Gu, Dongmei Zhe, Minhua Zhao, Guodong Chen, Nhieu Ly, Paul E. Stutzman, Li Piin Sung, Tinh Nguyen, Joannie W. Chin
Polymers are widely used as exterior coatings in buildings, bridges, aircrafts and automobiles for both protection and aesthetic purposes. However, the service life of the applied coatings is limited due to the photodegradation of polymers induced by

Effects of filler type and content on mechanical properties of photopolymerizable composites determined using a two-dimensional gradient platform

February 5, 2009
Author(s)
Sheng Lin-Gibson, Li Piin Sung, Haiqing Hu, Aaron M. Forster, Nancy J. Lin
Photopolymerizable dental composites have complex processing conditions and multi-component formulations that affect the final properties. Combinatorial screening is a useful approach for evaluating multiple properties of the composites. A single test

Comparing Analytical Methods for Detecting and Characterizing Nanoparticles in Formulated Products

October 1, 2008
Author(s)
Katherine M. Tyner, Anna M. Wokovich, William H. Doub, Lucinda F. Buhse, Li Piin Sung, Stephanie S. Watson, Nakissa Sadrieh
To understand the extent of consumer exposure to nanomaterials as well as how nanomaterials impact consumer goods, it is necessary to detect and characterize nanomaterials in unmodified final products. Although there are pathways to characterize
