What they work on
- Determine how electric charge accumulation and decay during electrospray deposition control the microstructure and porosity of dielectric granular polymer films, by combining experiments with physics-based modeling.
- Build a physics-informed multivariate Gaussian process, a machine learning model that respects known physics, to merge simulation and experimental data and uncover unobservable deposition physics.
- Use 3D porosity profiling, which maps the open spaces inside a film, to measure how film connectivity develops and to refine models of particle behavior and charge decay.
- Develop a predictive framework for inverse mapping, which works backward from a desired film to the process settings that produce it, so that customized polymer films can be designed rapidly.
More about the research
In this method, an electric field breaks a liquid into tiny charged droplets that land on a surface and build up a film. Manufacturers have been slow to adopt it because no one fully understands how the process settings determine the final film. A key unknown is how electric charge builds up and drains away as the film grows. That charge behavior shapes the film's microstructure, including its porosity (how much open space the film contains).
Why it matters
A predictive framework for electrospray deposition could make it practical to produce high-quality, customized polymer films at scale and at lower processing cost. Industries that depend on such films, including microelectronics, healthcare devices and energy, could benefit from faster design and fewer trial-and-error experiments.
