At the Energy & Semiconductor Composites Laboratory, we explore liquid metal and functional composites for next-generation energy and electronic devices.
Beyond understanding thier fundamental material properties, we aim to develop innovative and sustainable materials technologies for the future.
Fundamental and Applications of Liquid Metal
1. Fundamental Property Study of Liquid Metals
Gallium-based liquid metal exhibits unique interfacial characteristics arising from the presence of a surface oxide layer, which is distinguish it from conventional metals or liquids.
Accordingly, we systematically investigate not only the fundamental properties of liquid metal but also its behavior under varying envirionmental conditions and substrate structures.
2. Liquid Metal Applications
Based on our understanding of its fundamental properties, we explore the application of liquid metal in a wide range of devices.
Composite Materials for Thermal Management and Packaging
1. Thermal Management Materials
We develop thermal management composites with engineered heat-transfer networks to meet the demands of highly integrated electronic devices, including semiconductors and displays.
2. Gas Barrier Films
We study gas barrier packaging materials that protect electronic devices, including semiconductors and batteries, from moisture and oxygen, which can otherwise degrade device percormance.
Hydrogel-based Energy Materials
Our laboratory studies hydrogel-based Thermally Regenerative Electrochemical Cycle (TREC) materials that can convert wasted thermal energy generated in everyday life into electricity.
