Water inside the low-dimensional carbon structures has been considered seriously owing to fundamental
interest in its flow and structures as well as its practical impact. Recently, the anomalous perfect penetration
of water through graphene oxide membrane was demonstrated although the membrane was impenetrable
for other liquids and even gases. The unusual auxetic behavior of graphene oxide in the presence of water
was also reported. Here, on the basis of first-principles calculations, we establish atomistic models for
hybrid systems composed of water and graphene oxides revealing the anomalous water behavior inside the
stacked graphene oxides. We show that formation of hexagonal ice bilayer in between the flakes as well as
melting transition of ice at the edges of flakes are crucial to realize the perfect water permeation across the
whole stacked structures. The distance between adjacent layers that can be controlled either by oxygen
reduction process or pressure is shown to determine the water flow thus highlighting a unique water
dynamics in randomly connected two-dimensional spaces.
