Abstract: Graphene sheets having a plurality of holes in their basal planes are described herein. Methods for making the graphene sheets can involve contacting graphene sheets with an activated gas that has contacted a helium or argon atmospheric pressure plasma. The size and/or number of holes introduced can be altered by changing the contact time, the stand-off distance, the activated gas concentration, and/or the plasma power. Polymer composites containing the perforated graphene sheets are also described.

Abstract: A method of manufacturing a graphene monolayer on insulating substrates from CVD graphene synthesis, wherein a metal foil (3) catalyst with a top graphene layer (1) and a bottom graphene layer (2) is obtained, by comprising the steps of:
- Applying an adhesive tape (4) to the bottom graphene layer (2) deposited at the bottom of the metal foil (3) in the CVD graphene synthesis by a roller,
- detaching the adhesive tape (4) and the bottom graphene layer (2) from the copper foil (3) via the application of heat, from 1°C up to 5°C higher than the release temperature of the adhesive tape (4) so that the adhesive layer (4) with the bottom graphene layer (2) can be removed, obtaining a metal foil (3) with a top graphene layer (2) sample, and
- transfer the top graphene layer (1) onto a substrate (6) via a sacrificial protective layer (5).

Abstract: The present invention relates to the novel material fluorographene (FG), methods of making fluorographene, and its applications in electronics and related fields. The fluorographene also finds use in improving the properties of composite materials by incorporating the fluorographene of the invention with one or more materials such as fluoropolymers (FP) and the like. Conventionally, FP inter-chain interactions are very weak but spread over the area of FG, FG is able to act as a very effective and compatible reinforcement.

Abstract: Graphene is chemically modified by a process resulting in the introduction of functional groups located only at an edge of the graphene plane. The functionalised graphene finds uses in numerous applications and further chemical synthesis, including a process for coupling an organic or inorganic moiety to the graphene plane via the edge-located functional group. The disclosed products and processes provide highly flexible platforms for the integration of graphene into a variety of applications.
