Graphene Oxide Membranes: A Scalable and Efficient Application of 2D Materials

Since the first report on producing the two-dimensional (2D) material graphene in 2004, there has been considerable time and money invested into developing new graphene-based technologies. These aim to exploit the remarkable properties of graphene including its strength and electrical- and thermal- conductivity. At a basic level, transmission electron microscopy (TEM) image contrast is caused by the scattering of electrons and is dependent on the thickness and composition of the sample material. The ultimate thinness of graphene, combined with the low atomic number of carbon, provides the ideal blueprint for a low-contrast TEM support. Producing graphene and transferring onto a TEM support grid is difficult to carry out at large scale and high yield.
