Frequently Asked Questions
A: The GO is a polydisperse material where most of the particles have a size around 15 μm, as shows the next results measured by laser diffraction:
- - D90 29.05 - 32.9 μm
- - D50 14.30 - 16.6 μm
- - D10 5.90 - 6.63 μm
A: GO is extensively washed and some metal traces can be found in ppb.
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.
