High Pressure Induced Novel Structures in Carbon Nanomaterials


摘要/Abstract:
The phase transformation of nanomaterials under high pressure have attracted growing research interest due to the appearance of nanometer scale size effect and the novel high pressure behavior which is hardly discovered in their corresponding bulk samples. Deeply understanding those unusual high pressure structures and physical phenomena unveils new aspects of the intrinsic physics of nanomaterials. Carbon nanomaterials, such as nanotubes, fullerene, provide us ideal carbon sources to study novel phase and design new carbon materials induced by high pressure. Raman spectroscopy is a very powerful tool to study the structure of carbon material. In this presentation, in situ high pressure Raman technique will be introduced and several examples on high pressure induced novel structural phase transition in recently studied typical nano-confined carbon materials will be also outlined, including high pressure induced polymerization C60 in nanotube (peapod), unique long range ordered crystal with amorphous nano clusters as building blocks in solvated fullerene crystals which brings new physical insight to understand order and disorder concept and new approach to design superhard carbon materials, high pressure induced reversible polymerization in doped fullerene single crystal as well as high pressure and high temperature induced polymerization in fullerene nano crystals with fullerene cage as building blocks. These studies show that high pressure is a powerful tool and provides a new dimension for study of nanomaterials.
