Researchers from Imperial College London and the University of Birmingham have designed a novel technique for large-scale production of graphene with real-time monitoring. The study provides a viable route for controllable and customizable mass-production which could be adopted for other 2D materials.
Graphene is currently produced through a variety of methods, roughly divided into bottom-up and top-down approaches. Bottom-up graphene production builds layers atom-by-atom, making a high-quality product but with a drastically time-consuming process. Top-down graphene production is typically much faster and has the potential for large-scale production, but the quality is usually lower. Top-down processes begin with graphite which is split into different layers using a technique known as exfoliation. In this study, the team set out to produce a scalable method for top-down production which would result in a consistently high-quality graphene product.
