Will Graphene replace Mylar?

If this is a graphite / carbon long chain, it is possible that it is a conductor or semiconductor.....(properties of both insulator and conductor...) like silicon or germanium. Generally these are 'metaloids'....the elements between metals and non-metals on the periodic chart.

You might think of it as a sheet of 'buckyball'

If it is indeed a conductor, all bets may be off. If an insulator, it may be possible to change the properties thru some kind of doping of strips or coil structures IN the bulk material. You could make Magnepans by the yard....or any length you desire.

I'm gonna look this stuff up. I wonder if it has been characterized yet and what its bulk properties are?

thanks for heads up.

Today, we will have trouble imagining where this stuff is going? A material with these properties can be used in ways we simply can't imagine.

Cone replacement material? Think bigger.
The 'ultimate' ribbon tweeter? Likely.
A mylar-less Magnepan? If it can be fabricated with built in conductive loops, so you don't need wire or QR glued to sheet? Absolutely.

Automotive uses? Engineering uses?

I looked up the Wiki on this stuff and it is way over my head. I'm sure the brain guys are working right now on uses....and ways to make bunches of it real cheap.
