內容摘要	Graphene, a single layer of carbon atoms bonded into a two-dimensional honeycomb crystal structure, has attracted a great deal of attention since its discovery in 2004. Much research has been focused on developing routes for obtaining large sheets of monolayer or bilayer graphene. This has been recently achieved by chemical vapor deposition (CVD) of CH4 gases on copper or nickel substrates. But methane is extremely flammable and may form explosive mixtures with air. Here we report the CVD growth of continuous, single- and few-layered graphene films on copper foils with a solid-phase carbon source--polyethylene (PE)-- as the precursor under atmospheric pressure. This polymer precursor-based CVD synthesis provides a new route for simple, inexpensive, and safe growth of graphene thin-films. Another advantage of this approach is that the growth rate does not depend on the gas flow field as conventional gas-phase CVD does. Thus large-area growth of graphene sheets with uniform thickness is possible
