Investigation of the process of adsorption of C20 fullerenes on the surface of carbon nanotubes to create nanomechanical complexes

In various fields of science and technology in recent years, the main objects are nanometer-scale objects. These are fullerenes, carbon nanotubes, nanocomposites, thin- film multi-layer structures, etc. Nanostructured solids formed from these particles or clusters attract the attention of researchers because they can be used in a wide variety of fields: from science to industry. The predisposition of carbon to form surface structures is manifested in its new forms - fullerenes and nanotubes. These are structures that have unique physical and chemical properties. The simplest carbon nanotube consists of a single sheet of carbon atoms called graphene, which is rolled into a tubular shape. The diameter of nanotubes is in the range of several nanometers, and their lengths are usually several micrometers.By combining carbon nanotubes with fullerenes, various systems can be obtained that can be used as elements of mechanical nanodevices. However, it is necessary to find out the mechanisms of the processes that lead to the creation of such systems. Therefore, this paperpresents the results of the theoretical study of the interaction of carbon nanotubes with C20 fullerene. The main regularities of the structure, formation mechanisms, energy characteristics and electronic properties of the complexes of interacting carbon nanotubes and fullerene C20molecules have been determined. Theoretical studies were performed using the molecularcluster model and the calculated semi-empirical quantum chemical scheme MNDO.
