Perfect 2D Ceramic Films from Graphene Precursors

In this regard 2D materials, such as oxide (GO), have been used as matrices to develop oxide . The way researchers have achieved this so far, is by inserting metal ions between the multilayer stacks of GO, a process that has allowed them to move in the direction of producing multilayer metal oxide films. This process, however, does not typically produce true atomic-scale growth of platelet crystals, but rather fragile 2D assemblies of particles separated by large unfilled spaces that are responsible for poor mechanical properties.

In a study published in Advanced Materials, Liu et al. from Brown University found a way to overcome this limitation and grow fully-dense, space-filling ceramic films. In their study, they demonstrate a new approach in graphene-templating, based on “metalized graphene ink” precursors engineered to ensure colloidal stability over a wide range of metal-carbon ratios.
