Hi tomizett,
Thanks for your reply.
You might be right about asking graphene related questions on a chemistry forum.
It seems that graphene _is_ available commercially in China (as you might expect)
But there's various forms of graphene... most are not the real McCoy.
There's a graphene oxide product (which i understand is a powder), which looks promising.
These are available on alibaba.com. Most companies want to sell you kilogram volumes
but there are some companies that will sell small quantities, like one gram, or 10 grams.
I was hoping for a graphene paint that i could apply to both sides of a good insulator.
It's not clear to me whether this exist, or not: I need to do more googling.
It's also possible to buy graphene water filters. There's a company in USA that is
claiming they can desalinate sea water at 1/9th the cost of conventional methods.
This might prompt new attempts at greening the deserts in Israel, Saudi Arabia,
various African countries... etc.
This also offers hope of finding an inexpensive way of removing fluoride from
drinking water (which is left in situ by regular water filters).
I will update this thread as i learn more.
