Summary of Research
Ultrathin liquid polymer films play a critical role in numerous physical phenomena and engineering applications including soil science, lubrication, manufacturing, cosmetics, and food processing, among many others. How a liquid polymer film interacts with and adsorbs onto a surface determines properties such as surface conformation, adherence to a substrate, and how the liquid film will reflow depletion zones, which are often critical to performance. Therefore, understanding the physical mechanisms that govern how a liquid initially adsorbs onto a surface and spreads is crucial to designing systems and devices that rely on micro- or nanoscale mechanisms.
Polymer film behavior can be controlled through modification of surface interactions. However, because surface interactions occur at very small scales over very short time frames, capturing this physical behavior through imaging is challenging. Thus, we use a molecular modeling approach to characterize the physical mechanisms that govern liquid polymer spreading on the nanoscale as a function of environmental and design parameters. This model allows us to: obtain a fundamental understanding of ultrathin polymer liquid film spreading, derive design guidelines for complex nanoscale systems, explain experimentally observed phenomena documented in the literature, and unify many years of liquid polymer spreading research. Thus, this research aims to address the challenges that currently limit the effectiveness of ultrathin liquid polymer films used in a variety of engineering applications and potentially facilitate progress in other research fields such as miniaturization of electronic components and the implementation of previously unattainable technologies such as such as nanoscale-motors, biomedical nanodevices, and surfaces with dynamically tunable wettability.
