Sounds like interesting stuff. If it's cheap enough and can be wrapped tightly enough at the most basic level it'd be great for wrapping P60's.
Interesting read. Thanks for sharing.
Now where can I get some? :)
Now that's the real issue. Looks like it's made to customer spec which would be far too expensive for normal mortals. With any luck someone will buy a square kilometre of the stuff and sell it off in useful sized pieces.
Probably not yet on the market - it was at a trade show.
This stuff is a poor material for bridging gaps. As a wrap, heat is transferred across it’s thickness where conductivity is only 26W/m. Aluminum foil is over 5 times greater. This is not a TIM and still requires one for it’s intended purpose. This stuff is design to work like a heatpipe where the thermal path is along it’s length and width to move heat far away from the source and dumped.
True - I wasn't thinking about its 2D nature. Might still have its uses if the edges were embedded in a metal body though.
that could have lots of interesting applications if it ever falls to consumer level pricing
It’s being done by stacking sheets and taking a thin slice of the end grain. The procedure hasn’t quite been perfected but I bet it’ll be commercially available within a year. 
Available at farnell for a while:
i wouldn’t count on available in a year, thats a common claim, though even more common is 2-5 years, those almost never appear either, though i would be happy to be proven wrong
And at about $2-3 per square inch according to Farnell UK the prices need to come down a lot before I'll be getting any.

Dispels heat even more efficiently, and stronger to boot.
Carcinogenic though is a major possible detractor.
Carbyne is another interesting recent discover.
Appears the 6th element poses the potential for vast scientific advancements and here we are worrying about it’s production resulting in waste material and global warming 
That’s still about 20 times higher than most thermal compounds…
