Graphene Support Films
PELCO® Graphene TEM Support Films & Substrates
for TEM, SEM, SPM & Research
Pelco Graphene products are available on a variety of substrates including lacey carbon, 300 mesh Cu grid, 2000 mesh Cu grid, holey silicon nitride, and ultra-flat SiO2.
The Graphene is available in different thicknesses: single layer, 2-layers, 3-5, and 6-8 layers. Graphene sheets with thicker layers are available by special order.
Graphene on Lacey Carbon
The PELCO® Graphene TEM Support Films are suspended on a lacey carbon film on a 300mesh grid (#01895). The Graphene films we offer have either single, 2, 3-5, or 6-8 layer Graphene sheets and cover the entire TEM grid.
The usable area is around 75% due to some unavoidable folds and wrinkles in the Graphene sheets. Graphene, with its unique properties, offers a support film layer that is more conductive and also much thinner than the average carbon support film.
Although it is a crystalline support film, its contribution to signal formation is relatively low. This makes the single and 2-layer Graphene support film ideal for high resolution imaging, imaging of nanoparticles and imaging of weak contrast materials/interfaces.

- The thickness for a single layer of Graphene is approximately 0.35nm, Transparency is in the order of 96.4%.
- The thickness for 2 layers of Graphene is approximately 0.7nm, Transparency is in the order of 92.7%.
- The thickness for 3-5 layers of Graphene is between 1.0 – 1.7nm, Transparency ranges from 90.4 – 85.8%.
- The thickness for the 6-8 layers of Graphene is between 2.1 – 2.8nm, Transparency ranges from 83.2 – 78.5%.
The PELCO® Graphene has an in-plane modulus of 0.9TPa, compared to 1.0 TPa for Graphene produced by the Scotch Tape™ method.
Comparison of the diffraction pattern of Graphene on copper mesh coated with a lacey carbon film measured with:
- (a) a transmission electron microscope (TEM) at 80 kV and
- (b) the ultrafast electron diffraction (UED) setup at 6 kV.
The line profiles in (c) correspond to the highlighted regions in the diffraction patterns in (a) and (b).
These data have been normalized to the intensity of the first order peak. The widths and locations of neighbouring Bragg peaks were used to estimate the transverse coherence length of the UED setup.

Graphene on Ultra-fine 2000 Mesh Copper TEM Grids
This Graphene is directly supported by #G2000HA ultra-fine 2000mesh copper TEM grids with 6.5 m circular holes and a pitch of 12.5 m.
Transmission for this type of grid is 41%. The ultra-fine 2000 mesh TEM grid is supported by #4510 Synaptek 1 x 2mm slotted grid to give it the required stiffness.
Total thickness of the graphene, 2000 mesh and Synaptek grid stack is approximately 108 m.
The slot in the Synaptek grid is 1 x 2mm. The graphene sheet covers the complete TEM grid and leaves freestanding graphene covering the 6.5 m holes.
Total usable area is approximately 75% in the 1 x 2mm slot area due to unavoidable folds and wrinkles in the graphene sheet.
Available with single, 2, 3-5 and 6-8 layer graphene sheets.
Research-ready product, suitable for UHR imaging or as an experimental platform.
The specifications of the graphene are the same as mentioned above.
