Graphene is a 2D allotrope of sp2 carbon in the form of a planar monolayer. Compared with other nanomaterials, graphene has many unique chemical and physical properties, such as thermal conductivity, mechanical properties and gas impermeability. There are few reports on the application of graphene in the barrier properties of paper coatings. This article develops a graphene water-based nano-coating for high?grade packaging paperboard , which can give the paperboard better water-vapor, oxygen and sun-light barrier properties. Furthermore, the barrier properties of graphene coated paper are greatly improved by optimizing the coating process. In conclusion, graphene can be used in paper-coating slurry to produce a novel environment-friendly and high value-added paper.
