AMG019a Graphene on Lacey Carbon 300 Mesh Copper TEM Grids
Graphene is proving to be a remarkably versatile material. One of its many uses is transmission electron microscopy (TEM), a powerful imaging technology used by chemical, biological, and physical researchers. TEM captures images of microscopic materials by observing how they interact with an electron beam. The process involves placing the material on a specialized flat surface, or grid, designed to support the material and, at the same time, allow the electron beams to pass through. However, in some cases, the microscopic grid allows super small, nanoscale particles to fall through, making TEM difficult. Suspending a layer of graphene above the grid prevents particles from slipping through without altering the imaging process.
ACS Material offers a selection of TEM support films. Our TEM support films are supported by a lacey carbon film on a 300 mesh copper TEM grid and are created using trivial transfer graphene. Specifications of these advanced TEM grids include:
Thickness: Our 300 mesh copper TEM grids are available in either 1, 2, 3-5, or 6-8 layer configurations.
Substrate: The substrate includes a lacey carbon support film on 300 mesh copper TEM grid, featuring a grid hole size of 63 μm.
Coverage: Graphene coverage of the TEM grid is better than 75%; the graphene coverage is typically >75% of the whole 3.05 mm diameter TEM grid.
Appearance: The graphene film appears as a near-transparent to light-gray film on the surface of the lacey carbon mesh on a red-brown colored copper TEM grid.

AMG019c Graphene on Silicon Nitride TEM Grids
Graphene is proving to be an invaluable tool for TEM imaging. Graphene’s thinness and its superior electrical and thermal conductivity make it an ideal material to use as a support film on TEM grids. Additionally, graphene’s low atomic number minimalizes the scattering of the TEM electron beam, resulting in crisper images.
Continuous graphene films are required for TEM applications. ACS Material has developed a process to deposit high-quality CVD graphene films on silicon nitrate TEM grids using our proprietary trivial transfer method. The TEM substrate features a 3.0mm hexagonal silicon base that is 200μm thick covered with a silicon nitride membrane that’s 200nm thick. The graphene layer is available is 1, 2, 3-5, or 6-8 layers. Roughly 75% of the substrate is covered by graphene. Our TEM grids are free from contamination and facilitate high-contrast TEM images.
