摘要

Graphite intercalation compounds (GICs), a kind of donor-acceptor complex of host graphite with guest chemical species, are of interest to chemists and physicists because of their unusual properties. Much attention has been focused on the preparation and properties of GICs and their utilization. In recent years, we have attempted to intercalate two guest species together to study the chemical reaction of the first intercalated component ith the second one in the graphite interlayer space. As an example of inorganic reactions in the interlayer spacing of graphite, we reduced metal chloride with lithium 1,2. Atoms of zerovalent metal generated by the reduction start moving in the interlayer spacing of graphite and aggregate. This process results in the production of metallic particles in the graphite matrix. It is interesting to note that the size of the metallic particles produced could be explained on the basis of the movement of the metallic atoms in the graphite interlayer. For an example of organic reactions in the graphite interlayer, anionic polymerization of unsaturated hydrocarbon was studied 3-5. In the course of the characterization of the products, we have found a new type of carbon nanotube, which was given by polymerization in the interlayer and the subsequent removal of the polymer. In this paper we show a new method for obtaining carbon nanotubes.
