Graphene & Graphene Oxide Support Films for TEM References:


Application (continued)


graphene created by this technique possesses a highly ordered structure that is composed of 99% carbon by mass (1% hydrogen)[2]. This graphene was used to directly image gold nanoparticles and their organic surface molecules in both conventional and atomic-resolution TEMs at a level that greatly surpasses any current TEM support film[3].


Our graphene provides an invisible, crystalline background that enables the unrivaled TEM characterization of organic and inorganic nanomaterials.

Elemental analysis by FT-IR reveals that the synthesized graphene sheets are free of detri- mental oxygen functionalities. The FT-IR spec- trum of synthesized graphene is similar to that of highly oriented pyrolytic graphite (HOPG).


Ordering Information Graphene products come available in five different ways, allowing you to choose which is best for you


a) As a solution of 0.1 mg Graphene in 1 ml of Ethanol. A homogeneous solution will take less than 30 seconds to create by sonicating the Graphene-solvent mixture. One is able to coat their own grids using this solution.


b) As Graphene-enhanced lacey carbon TEM grids. 200 and 300 mesh. These grids are created by coating our existing lacey carbon grids with graphene. Through a unique drop method, solution is dispersed onto the Lacey Carbon Grid.


c) As dry, synthesized Graphene powder, 1 mg. Cat. No.
