Investigation of rhombic and other novel ices in graphene oxide membranes

Abstract: Graphene oxide membranes (GOMs) have shown significant promise as filtration devices, since they are impermeable to many substances but not to water. To explain the rapid transport of water through these membranes, it is thought that water forms a two dimensional rhombic crystal at room temperature which glides through nano-scale channels. Inelastic neutron scattering, with its high sensitivity to hydrogen-containing substances, is a very effective method to investigate new water structures and their dynamics. The vibrational modes of water are extremely sensitive to nano-confinement conditions. In our study we hope to confirm the existence of rhombic ice and investigate how it forms inside GOMs by investigating samples with different levels of hydration. We will also confirm that the intercalation of water in bulk graphite oxide produces different water structures to those in GOMs.
