Inter-layer spacing of graphene oxide flakes in the nematic phase and maps of the orientation and of the electric-field reorientation of the

Our previous SAXS measurement and our recent optical microscopy measurements, showed that graphene oxide (GO) flakes have different orientations in a confined space, inside a cell, depending on their positions within the cell and GO suspension concentrations, a new interesting properties for GO flakes. We plan to continue and complete our investigation the correlation between GO concentration and GO structural organization and their inter-flake spacing. Because of large inter-flake spacing of our GO suspensions, we need to use larger sample-detector distance ensuring a low q range accessibility (0.001-0.1 nm-1). In addition, we want to study the re-organization of GO flakes under electric field to understand the effect of concentration and flakes primary orientation on GO electro-optical switching.
