As material chemists, we aim to make and engineer nanomaterials to perform novel functions that do not exist in their bulk form. Two dimensional nanomaterials with very high aspect ratio in particular have the potential to behave and function differently or more superior than that of conventional macroscopic materials. Literature has shown that graphene oxide liquid crystals can facilitate the design and assembly of novel architectures into useful devices that can cater for a wide range of applications in energy, catalysis, sensing, to name a few. In this talk, our recent efforts in understanding the unique solution behaviour of this wonder material and their development into novel macroscopic assemblies with tailored properties and functions will be presented. In particular, emphasis will be placed on our recent developments on novel yarns, where graphene oxide liquid crystals play a key role in enabling new material development and design.
