FREQUENTLY ASKED QUESTIONS
A: The lateral dimensions of the GO are below 10 microns but usually around 1-2microns.
A: The surface area in dispersion form is not possible to measure since most techniques require the dry form and GO tends to agglomerate when water is removed. All GO surface is exposed to the water when it is in dispersion form so the surface area should be very high. The GO flakes are monolayer thick (2nm measured via AFM) in dilute dispersions.
A: Our GO is dispersed in water because it is very stable and no surfactant is needed. GO is functionalized with epoxy, alcohol and COOH groups on its edges. These functional groups make GO highly hydrophilic and also it loses part of its sp2 hybridization, making GO insulating. In order to recover conductivity is has to be reduced. We can work with other solvents, please contact us to know more about it.
