Abstract

The invention relates to a process for preparing concentrates of graphene nanoplatelets via the milling of graphite and exfoliants. The novel aspect of this process is characterised by the use of fatty acids and fatty acid esters as exfoliants of the graphene nanoplatelets in the milling system. Both the fatty acids and the fatty acid esters facilitate the delamination process, while simultaneously acting as stabilisers for the graphene nanoplatelets, permitting same to be easily dispersed in both solvents and polymers. The obtained concentrates permit the excellent properties of the graphene to be used, given that same does not undergo a chemical modification during the process.
