Evolution of interlayer water to form gel-like layers in graphene oxide

DOI

Graphene oxide is a heavily functionalised form of grapheme that is dispersible in water and other solvents. As water is added to pristine graphene oxide there is formation interlayer water which gradually expands to form a gel-like layer and, as more water is added a more dilute dispersion. We have studied the changes in water structure around graphene oxide nanoparticles and in this proposal we aim to look at the changes in the small angle part of the neutron scattering pattern as graphene oxide is progressively hydrated. Neutron scattering is the only technique that enables the unequivocal determination of the changing role of hydrogen as these materials evolve and the understanding gained from this experiment will be used to optimise the formation and structure of these important liquids and characterise the novel liquid crystal phases that can form at high concentrations.
