Surface Functionalization of Graphene Layer-Encapsulated Magnetic Nanoparticles by Inductively Coupled Plasma

Abstract:

Article Preview

The graphene layer-encapsulated iron nanoparticles were modified by pre-treatment of Ar plasma and post-treatment of NH3 plasma using an inductively coupled RF plasma. Analysis of XPS spectra have been carried out to study the effect of the plasma treatment on the improvement of enrichment of nitrogen-containing groups. The morphology of nanoparticles has been also analyzed by using a Scanning Transmission Electron Microscope (STEM) together with Energy Dispersive X-Ray Spectroscopy (EDS) elemental mapping to observe the distribution of elements.
