Designing Interfaces to Improve Energy Efficiency

Most of the projects in the Schadler group are focused on designing the filler / matrix interface of polymer nanocomposites for applications such as improved dielectric properties for more efficient electrical generation and transmission, or improved mechanical properties for reduced volume of plastics use. We are also building a nanomaterials data resource to bring the data for the community together in a way that allows for rapid design, development, and deployment of new materials.
