Abstract : This project aims at developing scientific underpinnings to tune thermal, electrical, and optical properties of materials. The project focuses on studying fundamental transport processes that determine the contrasts of thermophysical properties of composites and thin films, and various approaches to regulate heat transport processes. In the past three years, multiple methods to regulate heat transport has been studied: 1) thermal regulation of thermal and electrical conductivity in nanofluids, 2) thermal regulation of optical properties in thin film, and 3) thermal regulation of phase transition for efficient steam generation. Besides thermal regulation, we also develop an electrochemical method to regulate thermal conductivity in battery materials. Both experiments and modeling have been carried out in to advance the fundamental understanding of transport processes during switching of thermophysical properties. In the following, progresses in these fields will be reported in details.
