It seems that in order to act as a superconductor, graphene must be in its 2-dimensional form, a one atom thick layer. I am trying to visualize how that works in the context of a paste you can apply to the surface of an electrical contact junction.
Graphene *is* an allotrope of carbon that is one atom thick. That's simply what defines it. You don't get other forms of graphene. You do get different sizes of graphene particles,etc, but they are all one atom thick.
Also it's not a superconductor, it's just a very good conductor, better than silver and copper.
I should not have used the term "superconductor", which has a specific meaning. I meant "super" as a conductor.
The chemistry is very complex, as I mentioned and you probably know better than I, but it seems to me that the conductivity of "graphene" is not always the same in all of its potential commercial forms (graphene flakes, graphene oxide, CVD graphene, for examples). That's what I was referring to. In certain complexes that might impeded the degrees of freedom of the pi electrons, doesn't the conductivity suffer, at least a little bit?
