Monolayer graphene film is grown by CVD processing onto copper foil, then transferred onto PET (Polyethylene terephthalate)
Properties of Graphene Film on PET:
The graphene coverage is about 95%
The graphene film is continuous, with occasional holes and cracks
The graphene film is polycrystalline, i.e. it consists of grains with different crystallographic orientation
Sheet resistance 660-1500 Ω/square
PET Thickness: 7 mil=175 micron
Please note that it is difficult to obtain a Raman spectrum of graphene film directly on PET due to a strong background signal.
Transparent conductive coatings (TCO)
We can manufacture custom, large-size coatings, and use different shapes and types of plastic materials. You may also send us your own substrates for coating. Few-layer graphene coatings with a lower sheet resistance and lower transparency can also be prepared. Please contact us for a quote.
Our graphene films are made by a PMMA assisted transfer method. Please refer to the references below for more details.
