Functional surfaces of carbon materials

Many forms of carbon allotropes have been discovered and are intensively investigated due to their unique properties. The potential use strongly depends on defined surface functionalities and also on tuning of bulk properties. Current research topics at the IOM include modification of carbon materials like graphene, nanoparticles, nanotubes or nanodiamonds by means of high energy electron irradiation. For example, the radiation-chemical reduction of graphene oxide provides a completely new approach (“green chemistry”) for the large-scale production of graphene-like materials for supercapacitor electrodes; the controlled formation of color centers in nanodiamonds offers high potential for biomedical applications and as sensors. State-of-the-art analytical methods are available for characterization of surfaces and bulk structures and of optical, electrochemical or biochemical properties.
