The PELCO®Graphene Oxide films are based on the single and 2-layer PELCO®Graphene Films. The form in which they are offered is the same as the graphene films with the difference that the graphene films are oxidized using a proprietary oxidization process. This makes the films hydrophilic and more suitable for life science applications and research.
The graphene oxide films cover the entire lacey carbon, holey silicon nitride or the silicon dioxide substrates.
The user can expect to find around 70% graphene oxide coverage. Due to the fabrication process used some 10-100nm diameter pores are to be found randomly scattered about the graphene oxide film. In spite of this, we are convinced that this graphene oxide film is superior to the graphene oxide flakes which are offered by others.
The thickness of the single layer of graphene oxide film is 0.8 - 1.2nm as measured by EELS
The thickness of the 2-layer graphene oxide film is 1 - 1.5nm as measured by EELS.
2-layer Graphene Oxide Film on Lacey Carbon
EELS Spectrum from a 2-Layer Graphene Oxide Film on Lacey Carbon
The basic structure is the same as the graphene TEM supports; Lacey carbon on a 300mesh Cu grid and on top of the Lacey carbon is the graphene oxide. The graphene oxide films are research ready and offer large areas of graphene oxide over the complete TEM grid area. Available in packages of 5,10 or 25.
