Light Yet Strong-Inspired by Egg Whites

A research team led by Dr. Hyun-Ae Cha from the Nano Materials Research Division at the Korea Institute of Materials Science (KIMS) has developed a high-performance heat-dissipating composite material that achieves both eco-friendliness and low-cost processing. The team utilized a protein foaming process based on egg whites to create a three-dimensional magnesium oxide (MgO) heat-dissipating structure, which forms efficient thermal pathways that enable rapid and effective heat transfer. As a result, the developed material demonstrated a thermal conductivity up to 2.6 times higher than that of conventional heat-dissipating composites.
