Congratulations to Dr. Peter Chung, who recently successfully defended his PhD thesis entitled "The Elastic Mechanical Properties of Supported Thin Polymer Films".


Enabled by molecular design principles, a new generation polymers and polymer-based materials have been created for diverse technological applications that include: batteries, organic solar cells, nonvolatile memory, functional coatings and gas separation membranes and wearable fabrics with sensors. A primary goal is to make devices smaller, more efficient, and smarter. Despite the success, important challenges limit full realization of the promise of polymers. These challenges include understanding how the physical properties, and morphological structures, of polymers deviate from bulk when confined to increasingly smaller dimensions (nanometers to tens of nanometers).


We explore fundamental questions of polymer physics that have major implications for critical technological applications. For instance, we manipulate the morphology of conductive polymers, ranging from molecular orientation to macroscopic alignment, in order to enhance the performance of transistors and other electronic devices, including organic solar cells.




On the other end of the spectrum, non-conductive synthetic polymers are widely used as dielectric components of devices or functional coatings. We design specific morphologies, by taking advantage of intermolecular forces, for different applications.




Our studies of their behavior at the nanoscale, from dielectric to mechanical and to transport properties, provide important insights for materials design. As part of our new collaborations with our colleagues in the Biointerfaces Institute, we also image and probe the time-dependent biomechanical properties of live tissue cells, which are a crucial component of the identification and targeted treatment of cancerous cells.
