Sony Take Record For Largest Graphene Sheet Ever Produced

There can be little doubt that Sony’s announcement of a record breaking 100m graphene sheet will have set gift wrap manufacturers’ hearts racing. The prospect, however, is not that graphene will be the new big thing in Christmas wrapping paper but that with the development of new technologies and graphene products the long tradition of high-tech gift giving will continue.

It may be too soon in the development cycle for graphene products to be gracing the shelves of department stores but with Sony’s latest improvement in large scale graphene manufacture the promise of graphene phones with flexible screens and of portable rolltop computers that bring a whole new meaning to the word scroll may have come a step closer.

Sony Corporation’s innovation in the production of graphene sheets is the result of a hybridisation of CVD and roll-to-roll technology that produces graphene on a copper substrate at 1,000°C. The resulting sheet vastly improves on the previous largest produced which was Samsung’s 40′ colossus. The team were also able to produce a transparent conductive film by transcribing the graphene from the copper substrate to a polyethylene terephthalate base.

Sony is expected to deliver a lecture on their latest technology during the Autumn meeting of the Japan Society of Applied Physics (JSAP)  to be held at Ehime University from Sept 11 to 14, 2012 (lecture number: 14a-C1-11).
