Beware of new material claims - the case of graphene

WOW! You just gave them two wonderful, or not so wonderful, new  ideas for the use of Graphene:
A Powdered Graphene Supplement to mix with ones breakfast drink and Invisable Killer Thread.
I think you're on to something......Jim

Mix graphene with silly putty call it G- putty and take your  blood pressure and monitor spider footsteps. 

The thing about graphene is that a lot of its amazing properties are only valid when you have continuous perfect sheets of it- something that as far as I know is impossible at the moment. It has a very high electron mobility, but that works out to produce a resistivity of about 10nohm.m in bulk, and that's only if you can make a perfect multilayer structure that maintains the properties of a single sheet. This is only about 40% better than copper which is 16.8nohm.m, and that's easy to make nearly perfect.
That conductivity is not maintained if the sheets in the multilayer structure have dislocations. So why is it better than copper?

Based what one can read about and discern about what Graphene is, I suspect there is a lot of claimed "graphene" out there that is most likely just mere overpriced carbon at best. Just a hunch. You never know when it comes to marketing....

@geoffkait ..  who’s manufacturing the “tons” of graphene. Give us the details.
