DISPERSIBLE EDGE FUNCTIONALISED GRAPHENE PLATELET

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. 本公开提供了一种可分散石墨烯薄片及其制造方法。石墨烯薄片10的结构包括石墨烯基础层1，其上堆叠有至少一个石墨烯不连续层2、3、4，其中该基础层上面的每个石墨烯层具有比其在之上堆叠的层更小的表面积。该基础层和堆叠在其上的这些不连续层的边缘都被至少部分地功能化5，提供具有归功于该基础层的石墨烯样特性和归功于每个薄片上功能化基团的量增加的相对高分散性的结构。这些薄片可以用于多种应用，例如用于电极或复合材料的生产中。
