Copper-Graphene Nanocomposite Cools Electronics Faster & Cheaper 56
samazon writes "North Carolina State University researcher Jag Kasichainula has developed a 'heat spreader' to cool electronics more efficiently using a copper-graphene composite, which is attached using an indium-graphene interface film. According to Kasichainula, the technique will cool 25% faster than pure copper and will cost less to produce than the copper plate heat spreaders currently used by most electronics (abstract). Better performance at a lower cost? Let's hope so."

Industrial diamond is not terribly expensive. It can be had for about 2 grand per kilo. Admittedly this is a good deal more than copper, but this graphene composite may be cheaper to manufacture than diamond.
