Bluestone Global Tech (BGT) announced that they are now offering a roll of 24" by 300" graphene film on copper (branded Grat-Film). This is the first time that such a large graphene sheet is available.

BGT's online shop currently offers graphene on PET, on Quartz and on SiO2/Si. Hopefully they'll add the new graphene-on-copper product soon - and then we'll know the price of this new product.
