摘要: A reinforced concrete material is described comprising a cementitious material (22) in which graphene is substantially uniformly distributed. A method of production of concrete is also described comprising the steps of forming a substantially uniform suspension (20) of graphene with water, and mixing the suspension (20) with a cementitious material (22) to form a concrete material (28).

摘要: Methods of producing a uniformly or substantially uniformly doped relatively large area multi-layered graphene element are described comprising the steps of placing the graphene element and a dopant under low pressure conditions, and holding the graphene element and dopant at an elevated temperature for a period of time while under the low pressure conditions. In one arrangement, openings are formed in a multi-layered graphene element of relatively large area prior to doping. In another arrangement, a relatively large area multi-layered graphene element formed by an epitaxial growth technique is used. The invention also relates to an element produced using the aforementioned techniques.

摘要: A method for use in the synthesis of graphene is described that comprises the steps of annealing a substrate in a hydrogen gas atmosphere, subsequently undertaking a deposition and nucleation step in which a relatively thick carbon layer is deposited onto the substrate and subsequently thinned to form small graphene islands or nuclei, undertaking a graphene growth step in which the graphene islands or nuclei expand and coalesce, and subsequently allowing the substrate to cool. A sensor 10 incorporating the graphene sheet is also described.

摘要: A method of producing a substrate provided with a shaped graphene material electrically conductive region is described, the method comprising applying a photoresist material to a substrate, shaping the photoresist material to cover at least part of the substrate that is not to be electrically conductive, depositing a graphene material onto the substrate over the shaped photoresist material, and subsequently removing the photoresist material. Also described are devices such as touch sensors and shaped light emitting devices manufactured using the method.
