  Scalable enhancement of graphene oxide properties by thermally driven phase transformation

  Graphene oxide sheets hold promise for a variety of applications but are disordered and inhomogeneous on synthesis. Although processes to resolve this exist they typically remove oxygen groups, affecting the sheets’ properties. Now, a scalable, mild thermal annealing procedure has been devised that enhances the optical and electronic properties of graphene oxide sheets through phase transformation, while preserving their oxygen functionality.

  Graphene oxide as a chemically tunable platform for optical applications

  Chemically derived graphene oxide (GO) has recently moved on from simply being a graphene precursor to attracting interest for its own properties. This Review discusses how the presence of oxygenated groups and domains of sp²- and sp³-hybridized carbons makes GO tunable and promising for various physical and biological applications.
