US Patent 7595111 - Continuous graphene sheet production

http://www.freepatentsonline.com/7595111.html

There has been some interest in recent years in graphene as a new electronic material having a high electron mobility. This patent discloses a manufacturing method which may help facilitate mass production of graphene-based electronics. Claim 1 reads:

1. A method of creating continuous, monoatomic thick, graphite ribbon/sheet structures comprising the steps of:

providing a rotating drum with a static layer of graphite as a formation surface for graphite ribbon/sheet, and,

providing precursor material(s) of graphite ribbon/sheet on said formation surface, and,

providing activation by laser means of said precursor material,

whereby said precursor material assembles to create a continuous monoatomic thick graphite ribbon/sheet structure.
