General description
This product is provided with a PMMA coating on top of the graphene in order to ease the transfer process and to avoid contamination. It′s a high quality product with great homogeneity.
Graphene Film:
- Growth method: CVD synthesis.
- Appearance (color): Transparent.
- Transparency: >97%.
- Coverage: >98%.
- Number of graphene layers: 1.
- Thickness (theoretical): 0.345 nm.
- FET electron mobility on Al2O3: 2000 cm2/Vs.
- FET electron mobility on SiO2/Si: 4000 cm2/Vs.
- Sheet resistance on SiO2/Si: 450±40 Ω/sq (1cm x1cm).
- Grain size: Up to 10 μm.
Substrate Cu Foil:
- Thickness: 18 μm.
- Pre-treated for easier bottom layer removal. Monolayer graphene on the back side of copper is partially removed, but not completely. Therefore, an additional treatment like RIE is needed before transfer to eliminate the bottom layer totally.
PMMA Coating:
- Spin coated for high homogeneity.
- Molecular weight: 495k.
- Thickness: <100 nm.
- PMMA model: 495k, A2.
Application
- Flexible batteries.
- Electronics.
- Aerospace industry.
- MEMS and NEMS.
- Micro actuators.
- Conductive coatings.

How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
Aldrich Products
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
Not Finding What You Are Looking For?
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
