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.
Graphene oxide supported by #21535-10 holey silicon nitride which has 2.5µm holes with a 4.5µm pitch in 200nm SiNx over a 0.5x0.5mm window size. The graphene oxide is deposited over the complete 3mm frame on the flat side. Available in packages of 5,10 and 25
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.
