Beware of new material claims - the case of graphene

Proper graphene is still a bear to produce. It is likely that many that tout ’graphene’ as inclusive...are touting a marketing definition.

(It’s an ’all things graphene’ link. It will help one get up to speed and up to the moment -- in graphene data)

I agree with teo_audio. Graphene is a terribly difficult material to make into products outside the lab. One group that is close to bringing a headphone to market with driver diaphragms made of graphene is Oro. You can search for them over on Kickstarter. And theirs is layered graphene, rather than unitary molecular graphene. Still, they are so rigid they claim to have almost no modal breakup. We’ll see when they ship in 2019!
