what exactly is 'electronic grade graphene'? the article isn't specific. how few layers can the process produce?

why aren't they producing it yet if it's so much cheaper?

are there any specs on it at all?

is it the same as opto grade graphene?

reminder? why, it was written in early 2015. what's the point in reposting it?

seems like a wishy-washy article to me. are we supposed to be worried about this?
