Graphene powder, synthesised
Graphene is the ideal support film for electron microscopy. Graphene is a single atomic layer of carbon atoms, tightly packed in a two-dimensional honeycomb lattice. This novel material is atomically thin, chemically inert, consists of light atoms and possesses a highly ordered structure. Graphene is electrically and thermally conductive and is the strongest material ever measured.
Applications
- Direct imaging of soft and hard nanomaterials
- Biodevices
- Single molecule gas detection
- Graphene nanoribbons
- Integrated circuits
- Transparent conducting electrodes
- Ultracapacitors
Elemental analysis by FT-IR reveals that the synthesised graphene sheets are free of detrimental oxygen functionalities. The FT-IR spectrum of synthesised graphene is similar to that of highly oriented pyrolytic graphite (HOPG).
The ultrahigh-quality graphene produced by the substrate-free gas-phase method has enabled the unsurpassed TEM imaging of organic molecules and the interfaces between soft and hard nanomaterials. The pure and highly-ordered sheets were used as a near-invisible support film to directly image the atoms in a gold nanoparticle and its surrounding citrate coating. The results showed that the synthesised graphene can be used to directly observe nanoparticles functionalised with a diverse range of molecular coatings, such as proteins and DNA.
