| description | The present disclosure provides a dispersible graphene platelet and a method of making same. The structure of the graphene platelet 10 comprises a base layer 1 of graphene on which at least one discontinuous layer 2, 3, 4 of graphene is stacked, with each layer of graphene above the base layer having a smaller surface area than the layer it is stacked upon. The edges of the base layer and the discontinuous layers stacked upon it are all at least partially functionalised 5, providing a structure with graphene-like properties owing to the base layer and relatively high dispersibility owing to the increased amount of functionalised groups on each platelet. The platelets may be used for a number of applications, for example in the production of electrodes or composite materials.
La présente invention concerne une plaquette de graphène dispersible et un dispositif pour sa fabrication. La structure de la plaquette de graphène 10 comprend une couche de base 1 de graphène sur laquelle au moins une couche discontinue 2, 3, 4 de graphène est empilée, chaque couche de graphène au-dessus de la couche de base présentant une surface plus petite que la couche sur laquelle elle est empilée. Les bords de la couche de base et des couches discontinues empilées sur celle-ci sont tous au moins partiellement fonctionnalisés 5, permettant ainsi d'obtenir une structure présentant des propriétés de type graphène grâce à la couche de base et une dispersibilité relativement élevée grâce à la quantité accrue de groupes fonctionnalisés sur chaque plaquette. Les plaquettes peuvent être utilisées pour un certain nombre d'applications, par exemple dans la production d'électrodes ou de matériaux composites. |
