Using a series of novel flash‐freezing experiments, the formation mechanism of free‐standing, paper‐like materials produced by vacuum‐assisted self‐assembly (VASA) of graphene oxide (GO) suspension has been elucidated. A stop‐motion animation of the VASA process is created, showing highly ordered, hierarchically structured GO papers to have evolved via an intermediate self‐supporting phase formed by successive sheet aggregation processes at increasing length scales.
