The effects of nanoconfinement on the structural dynamics of water is of fundamental scientific importance in both natural and engineered environments. Here we present an experimental investigation of intercalated water in graphene oxide (GO) using ultrafast infrared spectroscopy. The water organization in a fluctuating network of intermolecular hydrogen bonds is different to bulk water due to the decreased symmetry and new interactions with GO functional groups. We discuss the structural response of this network to energy input and address the implications for the mechanical properties of multilayered composite materials like GO.
