91直播 leads global study to set graphene quality standard
Graphene could transform everything from electric cars to smartphones, but only if we can guarantee its quality. The University of Manchester has led the world鈥檚 largest study to set a new global benchmark for testing graphene鈥檚 single-atom thickness. Working with the UK鈥檚 National Physical Laboratory (NPL) and 15 leading research institutes worldwide, the team has developed a reliable method using transmission electron microscopy (TEM) that will underpin future industrial standards.
Researchers at The University of Manchester, working with the UK鈥檚 National Physical Laboratory and 15 international partners, have developed a robust protocol using transmission electron microscopy (TEM). The results, published in , will underpin a new ISO technical specification for graphene.
鈥淭o incorporate graphene and other 2D materials into industrial applications, from light-weight vehicles to sports equipment, touch screens, sensors and electronics, you need to know you鈥檙e working with the right material. This study sets a global benchmark that industry can trust,鈥� said , who worked on the research during his PhD.
鈥淓lectron diffraction has long been used to distinguish monolayer from few鈥�layer graphene, but it鈥�s often applied without a full treatment of uncertainties. By collaborating across 15 leading labs. including the original pioneers, we鈥�ve mapped the pitfalls and shown how to get reliable results鈥� added Dr Evan Tillotson.
鈥淲e鈥檝e designed this protocol so it works in real labs, not just in specialist centres. And for organisations without TEM capability, we can provide measurements commercially through our partnership with the ,鈥� said , Professor of Materials.
The findings are used directly within the international standard, currently in press and expected to be published in 2026. 鈥淭his work builds on the NPL Good Practice Guide 145 'Characterisation of the Structure of Graphene鈥� developed in partnership with the University of Manchester, and one of NPL's most downloaded guides.", notes , Principal Scientist of the Surface Technology Group and Advanced Materials Strategy Lead at NPL.
