The present invention discloses a method for transferring a thin film from a first substrate to a second substrate comprising the steps of: providing a transfer structure and a thin film provided on a surface of a first substrate, the transfer structure comprising a support layer and a film contact layer, wherein the transfer structure contacts the thin film; removing the first substrate to obtain the transfer structure with the thin film in contact with the film contact layer; contacting the transfer structure obtained with a surface of a second substrate; and removing the film contact layer, thereby transferring the thin film onto the surface of the second substrate.

Cross-linking moiety

A functionalised graphene oxide and a method of making a functionalized graphene oxide comprising: (i) oxidizing graphite to form graphite oxide wherein the graphene sheets which make up the graphite independently of each other have a basal plane fraction of carbon atoms in the sp-hybridised state between 0.1 and 0.9, wherein the remainder fraction comprises sp-hybridised carbon atoms which are bonded to oxygen groups selected from hydroxyl and/or epoxy and/or carboxylic acid; and (ii) exfoliating and in-situ functionalizing the graphite oxide surface with one or more functional groups such that fictionalization of the surface is effected at a concentration greater than one functional group per 100 carbon atoms and less than one functional group per six carbon atoms. The functionalized graphene oxide is dispersible at high concentrations in appropriate solvents without aggregating or precipitating over extended periods at room temperature.
