Will Graphene replace Mylar?

The 2010 Nobel Prize for physics has been won for creating a substance called Graphene which is thinner than an atom and a good conductor of electricity. Wouldn't it be ideal for making the ultimate electrostatic speaker or Magnepans? Graphene probably costs a bomb now, but in a few years its cost will come down. Martin Logan please note. They already have I am sure. Adios Mylar?

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.

Mhhhh! Maybe Graphene nano-ribbons are the way to go!

Will Graphene replace Mylar?

That's the wrong question, I think. Mylar is simply the support for the conductive aluminum layer in a planar driver - since graphene is as conductive as copper and as strong as steel, there will be no need for the support layer. Imagine pure ribbons, one atom thick, carrying the signal in a magnetic field. They will be the ultimate ribbon driver if the cost and scale-up hurdles can be managed!
