The performance of graphene-based bulk materials is dependent not only on the structure and properties of individual sheets, but also on the intersheet interactions and their hierarchical texture or its supramolecular structure. Our group has been studying the supramolecular chemistry of chemically converted graphene and how non-covalent interactions can be utilized to create carbon-based functional soft materials that are difficult to obtain with other techniques. We have demonstrated that hydration of graphene not only enables its solution processability, but more importantly, offers simple and scalable ways to assemble graphene into well-controlled nano-architectures with extraordinary macroscopic properties. This talk will highlight how the architecture of graphene-based gels can be engineered to enable new functions that are difficult to achieve with traditional materials.
