The Voice of Measurement and Testing

The world's first ISO graphene standard has been published. The standard will provide consistency across the emerging world-wide graphene industry and accelerate the 2D material's commercial exploitation...

The new international standard, led by the National Physical Laboratory (NPL), defines the terminology used to describe the many different forms of graphene, supporting companies in the testing and validation of the 'wonder material'. This will help unlock new applications, drive down manufacturing costs and open up industrial-scale use of graphene for applications from next-generation computer chips to smart sensors in clothing.

Interest in graphene and related 2D materials continues to grow both commercially and academically, and many industrial sectors look set to benefit from the unique properties of these materials, areas such as electronics, energy storage, nanocomposites and sensors, with over one hundred companies worldwide now producing or using graphene.

However, while terms such as 'epitaxial graphene', 'graphene oxide' and 'few-layer graphene' are commonly used across industry, prior to the publication of this new standard, there were no universally-agreed definitions – in some cases, material that is hundreds of layers thick has been incorrectly branded 'few-layer graphene'. Inconsistencies like this prevent companies that are developing new products from fully understanding the properties of commercially-available graphene-based materials and selecting the material best suited to their application. This is a key barrier to commercialisation of new products and prevents trust in the supply chain.
