摘要：

We report on successful intercalation of multiwall (MWNT) and single wall (SWNT) carbon nanotubes with alkali metals by electrochemical and vapor phase reactions. A LiC10 compound was produced by full electrochemical reduction of MWNT. KC8 and CsC8-MWNT first stage derivatives were synthesized in conditions of alkali vapor saturation. Their identity periods and the 2 x 2 R 0 degrees alkali superlattice are comparable to their parent graphite compounds. The dysonian shape of KC, EPR line and the temperature-independent Pauli susceptibility are both characteristic of a metallic behavior, which was confirmed by C-13 NMR anisotropic shifts. Exposure of SWNT bundles to alkali vapor led to an increase of the pristine triangular lattice from 1.67 nm to 1.85 nn and 1.87 nm for potassium and rubidium, respectively.
