3-D Graphene: Super-capacitors from sugar bubbles

more »

Graphene sheets are immensely strong, lightweight and excellent at conducting electricity. Theoretically, macroscopical three-dimensional graphene assemblies should retain the properties of nanoscale graphene flakes. However, recent attempts to make 3-D graphene have resulted in weak conductivity due to poor contact between graphene sheets. Loss of strength is also a problem, and self-supporting 3-D graphene has not yet been produced.
