Nanomaterials like graphene give researchers and scientists a lot of hope for their future applications in a wide range of world-changing applications, but consistency and quality control remains an elusive challenge in graphene production.
A team from University of Sussex has developed a non-destructive, laser-based method for looking at the size and thickness of graphene particles. Dr. Matt Large of the School of Mathematics and Physical Sciences at the University said this of the study:
“Standards for measurement are a really critical underpinning of modern economies. It really comes down to one simple question; how do you know you got what you paid for?
“At the moment the graphene industry is a bit of a wild frontier; it’s very difficult to compare different products because there is no agreed way of measuring them. That’s where studies like ours come in.”
The team’s laser helps them look at particles as a whole and build a richly detailed picture of how particles are distributed in any given material. Since graphene is often used in precision scientific or electronic applications, knowing the quality of the material is key for accuracy and performance.
