Phys., 2013, 15, 2321-2327; doi: 10.1039/C2CP44593J FAQs Q: What is the lateral dimension of GO A: The lateral dimensions of the GO are below 10 microns but usually around 1-2microns. Q: What is the surface area of GO? 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. Q: Why is GO dispersed on water? Can I buy GO in other solvents? 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. Q: Will freezing cause damage to the GO water dispersion? A: Experiments have proven that no damage would be expected if the GO water dispersion was frozen during transportation or storage. MSE Supplies guarantees the high quality and best price on the market for our graphene products. Buying graphene products from MSE Supplies will save you ~50% or more compared to prices listed by other re-sellers such as Sigma-Aldrich. Q: What is the method of making the GO? A: A modified Hummers method is used.
