Graphene oxide (GO) has been recognized as a unique two-dimensional building block for various graphene-based supramolecular architectures. In this article, we systematically studied the three-dimensional self-assembly of GO sheets in aqueous media to form hydrogels. The gelation can be promoted by different interactions, including hydrogen bonding, π-stacking, electrostatic interaction, and coordination. Furthermore, lateral dimensions also have strong influences on gelation. resulting...
