Physical and Chemical Properties of Primers with Functional Additive Based on Carbon Nanotubes

Abstract

Carbon nanotubes are structures where, due to their ideal structure, there is no electron scattering on defects in the crystal structure, so that they have high conductivity and low heat release during the passage of current. Thus, carbon nanotubes that conduct heat well are a material that can be used to achieve high thermal insulation properties. The exceptional physical and mechanical properties of carbon nanotubes make it possible to use them as nanofillers in order to obtain new materials with predictable properties and characteristics. Due to their structure and geometry, CNTS have unique mechanical, sorption and other properties. The unique structure of CNTS provides them with high surface activity, because of which they are widely used as fillers and functional additives. Modification of the material by nanotubes can lead to a significant improvement in the physical and mechanical characteristics of the original systems, as well as to an increase in their energy – saving properties. To date, the creation of composite materials based on carbon nanotubes is one of the most pressing issues, and the study of physical, chemical and mechanical characteristics of nanocomposites remains relevant, has scientific and practical significance, since the creation of such materials opens up great opportunities for their use in various fields of industry. In this work the influence of carbon nanotubes on some physical and chemical properties of GF-021 applied on various surfaces, such as brick, wood, gypsum board been, investigated. The results of the experiments show that the functional additive based on carbon nanotubes favorably influences such properties of the GF-021 primer as the drying time and stability to the static action of a 3 % solution of sodium chloride.
