GRAPHITE NANOPLATELETS CHEMICAL CROSS-LINKING BY ELEMENTAL SULPHUR

The reaction of graphite nanoplatelets (GNPs) with elemental sulphur provides a mechanically stable spongy material characterized by good electrical conductivity and high surface development; such unique property combination makes these novel nanostructured materials very useful for applications in different technological fields. The carbon-sulphur reaction can be accurately investigated by thermal analysis (DSC and TGA) and energy-dispersive X-ray spectroscopy (EDS) combined to scanning electron microscopy (SEM). The thermal treatment required for the formation of electrically conductive mono-sulphur connections among the GNP unities has been investigated.
