Abstract
Low dimensional carbon based materials are strictly dependent from the intrinsic property of self-assembling. Three simple and fast methods to unzip Single Wall Carbon Nanotubes (SWCNTs) have provided different structural organization of graphite layers, observed by electron microscopy investigations. Our structural studies reveal the presence of a deviation from perfect crystal of the graphite aggregations, called turbostratic graphite, because of the presence of rotational and/or translational stacking faults of its hexagonal basal planes. Furthermore, one more different crystallographic phase of graphite with an orthorhombic cell and symmetry Cmma has been experimentally detected by Selected Area Electron Diffraction (SAED) analysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
