摘要

Densely assembled graphene-based membranes have attracted substantialinterest for their widespread applications, such as compact capacitive energystorage, ion/molecular separation, gas barrier films, and flexible electronics.However, the multiscale structure of densely packed graphene membranesremains ambiguously understood. This article combines X-ray and lightscattering techniques as well as dynamic electrosorption analysis to uncoverthe stacking structure of the densely stacked reduced graphene oxide (rGO)membranes. The membranes are produced by reducing graphene oxide(GO) membranes with hydrazine, during which the colloidal interactionsbetween GO sheets are modulated by the electrolyte solution. In contrast tothe common notion that direct reduction of densely assembled GO sheets inparallel tends to result in significant “graphitization”, this article unexpectedlydiscovers that the resultant densely packed rGO membrane can still retainthe interconnected network nanochannels and show good capacitive performances.This inspires the development of a hierarchical structural modelto describe the densely packed rGO membranes. This article further showsthat the nanochannel network can be fine-tuned at the sub-nanometer levelby tailoring the salt concentration and the reduction temperature to renderexceptional volumetric capacitance and good rate performance for rGO membraneseven with increased packing density.
