Abstract
► Aqueous dispersions of surfactant stabilised graphene were passed through a size exclusion chromatography column. ► The resulting fractions were drop cast onto grids and flake sizes measured using transmission electron microscopy. ► Thin films were vacuum filtered from these fractions and examined using Raman spectroscopy. ► The first fraction showed an increase in average flake size from that of the stock by a factor of 2. ► The flake D:G intensity ratio scales inversely with flake size showing defects to be edge related rather than basal plane.
