Graphene and bromine
Conundrum, Fri Oct 12 2018, 08:03AMHi all.
I might have found something interesting.
A little while back some researchers invented a way to make graphene a better conductor using bromine gas.
also relevant:
Seems that there might be a way to use a bromine *salt* instead in aqueous solution.
If so then it would be a very efffective way to make this compound and obviously upon removal it would retain its properties.
Wonder if anyone else has tried this?

Well, it makes sense that doping it with a bromide would make it a better conductor. At the scale of Graphene it seems that the salt would act almost like it is in solution when applied to the Graphene.

Yup. It appears that any halogen works but bromine is better.
(hint: I have a source but it is - problematical. )

Liquid or gaseous bromine is not 'friendly' to work with,
potassium bromide is available via eBay but I doubt there would be any reaction,
potassium bromate is also available and it is a fairly strong oxidiser so may work on its own,
but bromide plus bromate at low pH will release bromine, so may be useful ?

Worth a try, thanks.
Incidentally I might have found a way to enable "hyperconductivity", not RTSC but very close. Looks like some very simple chemistry can enable a material that contains no silver yet is more conductive than it in the bulk.
In this case it uses quantum effects to increase conductance, at the cost of making the resulting material brittle.
