Scholarcy highlights

  • Integration of individual two-dimensional graphene sheets into macroscopic structures is essential for the application of graphene
  • We report the direct synthesis of three-dimensional foam-like graphene macrostructures, which we call graphene foams, by template-directed chemical vapour deposition
  • A GF consists of an interconnected flexible network of graphene as the fast transport channel of charge carriers for high electrical conductivity
  • Even with a GF loading as low as ∼0.5 wt%, GF/poly(dimethyl siloxane) composites show a very high electrical conductivity of ∼10 S cm−1, which is ∼6 orders of magnitude higher than chemically derived graphene-based composites4. Using this unique network structure and the outstanding electrical and mechanical properties of GFs, as an example, we demonstrate the great potential of GF/poly(dimethyl siloxane) composites for flexible, foldable and stretchable conductors12
