A research team led by the National University of Singapore (NUS) has developed an economical and industrially viable strategy to produce graphene. The new technique addresses the long-standing challenge of an efficient process for large-scale production of graphene and paves the way for a sustainable synthesis of the material. Graphene is a two-dimensional material with a honeycomb structure of only one atom thick. Graphene exhibits unique electronic properties that can potentially be employed for a wide range of applications such as touch screens, conductive inks and fast-charging batteries. The difficulty to produce high-quality graphene affordably on a large scale, however, continues to pose hindrance to its widespread adoption by industries. The conventional method of producing graphene utilizes sound energy or shearing forces to exfoliate graphene layers from graphite, and then disperses the layers in large amounts of organic solvent. As insufficient solvent causes the graphene layers to reattach themselves back […]
