Abstract

In this paper, we study the electrical conductivity of nanostructured C60-modified aluminum, and the possibility of optimizing its electrical and mechanical properties. The model proposed allows estimating the electrical conductivity of the material at low surface filling factor. A number of samples with different C60 mass fractions and aluminum crystallites sizes have been obtained and investigated; a mean crystalline size, conductivity, and hardness of these samples have been determined. A theoretical model has been compared to the experimental data. The model is in qualitative agreement with the experiment. The X-ray photoelectron spectroscopy and Raman spectroscopy studies of the material structure indicate the presence of covalent bonds between the aluminum in the clusters and the C60 molecules, and they are consistent with the proposed shell model.
