Are graphite intercalation compounds stable in water?

I want to do an experiment with graphite sulfate, but I want to know if it will de-intercalate in a beaker of distilled water?


Thanks! 




According to [*"Graphite sulphate – a precursor to graphene", Siegfried Eigler, Chem. Commun., 2015,51, 3162-3165*](http://pubs.rsc.org/en/content/articlepdf/2015/cc/c4cc09381j):

This would seem to imply that it would indeed de-intercalate in a beaker of distilled water.
