Two British scientists won the Nobel Prize in Physics in 2010 for their contribution to graphene, however, graphene based materials have come to an awkward dilemma in recent years because there has been a big gap between its great prospects and the current application in practice. In 2018, Nature published a review article entitled The War on Fake Graphene, stating that the lack of relevant measurement and certification standards has led to a mixed and disorderly market of graphene, awash with a large number of graphite-like fake graphene with more than 10 layers of carbon atoms, severely impacting its related research and application.
To solve this problem, the New Materials Measurement Innovation Team of NIM has established a system of valid measurement methods for key multi-parameters of graphene based powder/slurry, and combined these measurement technologies for evaluation of graphene products, which has obtained international recognition through the domestic/international comparisons piloted by NIM. This system enables the market to distinguish between true and false graphene. In addition, NIM has led and participated in developing the national standards based on the mentioned achievements, and issued test certificates of graphene products to a third-party certification body, which has issued the first graphene product certificate in the world. This work has demonstrated the role that the National Quality Infrastructure (NQI) has played in the entire chain of graphene industry, which has helped to create a sounder and more standardized graphene industry and has boosted the confidence of producers and end users as well.
Graphene is an allotrope of carbon in the form of a single layer of atoms in a two-dimensional hexagonal lattice in which one atom forms each vertex.
