KAIST's discovery of graphene oxide liquid crystals in 2011 laid the foundation for 15 years of research worldwide, leading to technologies for producing graphene fibers with high strength and thermal conductivity. The fundamental materials research that helped bring antibacterial toothbrushes and functional sportswear to market is now advancing into materials for thermal management. Professor Sang Ouk Kim's team in the Department of Materials Science and Engineering has published a commentary in Nature Materials, examining recent advances in high-performance graphene fibers based on graphene oxide liquid crystals and their scientific significance. Graphene oxide consists of graphene, a single layer of carbon atoms arranged in a honeycomb structure, with oxygen functional groups attached. Graphene is strong and conducts heat and electricity well, but its poor dispersibility in water makes it difficult to process in liquid form. By contrast, the oxygen functional groups allow gr...
