Beware of new material claims - the case of graphene

Given that graphene is quite the in vogue material for audio applications I wonder how many (if any) of the vendors selling this are actually sourcing the real thing?

Graphene is easy to come by and is quite reasonably priced these days. https://graphene-supermarket.com/Pristine-Graphene-Monolayer-Flakes-50-ml.html

They supply micro-spectrographs of some of their products. The product I linked to is well priced and contains 99% single layer graphene. So rather than accepting an article that is issuing a broad warning without any investigation, people can find real graphene at reasonable prices with a small amount of research. I’m sure fraud is an issue. But remember that fraud occurs for anything of value. Cables, Rolex’s whatever. People can do a small amount of research to get the real thing.
