Graphene Nanoplatelets

AGMs technology stems from the development of ground-breaking ‘bottom-up’ reaction process for the industrial production of graphene nanoplatelets. We have built on this and have developed several proven manufacturing routes to consistently high quality and scalable graphenes

Across our product range, we offer graphene nanoplatelets that vary in number of atomic layers but typically have a thickness between 1 to 10nm with 1-25µm lateral platelet diameter, this gives aspect ratios up to 1:1000 and surface areas up to 700m2/g.

With the correct incorporated, graphene nanoplatelets have the potential to significantly enhance an array of properties including mechanical, barrier, thermal, lubricating and electrical performance in new and existing industrial systems.

We believe that the value of graphene lies in the ability to robustly transfer its intrinsic properties into dispersions, this creates products which possess specifically enhanced characteristics and enable formulator to innovate with graphene.

Graphene nanoplatelets are stacks of graphene layers in a two-dimensional nano particulate structure, their properties vary depending on a number of physical and chemical factors. The number of atomic layers, the platelet structure and morphology, the oxygen content and the lateral partical size for example all impact the performance of the graphene in the finished system.

At AGM, we pride ourselves on truly understanding how our graphenes work so that we can develop nanoplatelets that deliver real outstanding performance benefits in existing and new industrial products.  

Our graphene nanoplatelets are manufactured using a ‘bottom-up’ process proven to be consistent and scalable and our proprietary technology enables us to develop a wide range of nanoplatelet formats and structures. 

Using this process, our graphene is typically free from graphitic impurities, graphene oxide or transition metals – making it suitable for a wide range of applications.
