Nanostructuring graphene and graphitic substrates for controlled and reproducible functionalization

Final Report Summary - NANOGRAPH@LSI (Nanostructuring graphene and graphitic substrates for controlled and reproducible functionalization)

Graphene is a new class of promising material with exceptional properties and thus warrants a plethora of potential applications in various domains of science and technology. A prerequisite for the use of graphene in several applications is its modification in a nanostructured fashion, i.e. creating periodic features on graphene in the nanometer regime. Molecules are ideal to nanostructure graphene and change its electronic properties.

NANOGRAPH@LSI aimed to develop systematic experimental protocols for controlled and reproducible (covalent, non-covalent as well as the combination of both) functionalization of graphene and graphitic materials in a nanostructured fashion at the liquid-solid interface (LSI), along with the implementation of new nanoscale characterisation tools, targeting a broad range of applications in the fields of electronics, i.e. doping and sensing.

The project led to the development of protocols to nanostructure graphene and graphite by molecular adsorption, and provided detailed understanding of the factors such as concentration and temperature that influence the organization of molecules on these surfaces. In addition, protocols were developed to bind molecules chemically on graphene and graphite. Analytical and microscopy techniques have been approved to address the structure and properties of these nanostructured surfaces.
