The dissertation solves the scientific and technical problem, which consist in increasing of the technological equipment’s durability through usage of developed multifunctional epoxy nanocomposites with improved dielectric properties, as well as in establishing patterns of physical mechanical and thermophysical properties’ relationship with the structure of materials, which is regulated by the predicted adding into the binder of the modifier 4,4-sulfonylbis (4,1-phenylene) bis (N, N- diethyldithiocarbamate) and nanodispersed soot CARBON BLACK PowCarbon’s 2419G brand at the optimal content. The relevance of current researched area is derived to the fact that nowadays special attention is paid to the research of nanostructured polymeric materials as the most prospective multifunctional composites. The reason regarding mentioned relevance consists in the following: during transition from micro to nanosized particles, composite materials acquire new characteristics that are not achievable when usage of microparticles. Therefore, the introduction of nanodisperse fillers together with modifiers allows efficient and targeted formation of functional polymer composites with predetermined physical-mechanical, thermophysical and dielectric properties. Based on this, the development of modified epoxy composites by introduction of a nanodisperse filler with the selected physical chemical nature is derived to the relevance of their usage. In such case, the usage of these materials involves increasing the service life of the vehicles’ parts and mechanisms, which reduces the cost of their manufacture and repair. The purpose of the dissertation is an establishment of the main regularities for formation of modified and filled with nanodispersed carbon black (soot) epoxy multifunctional composites with high operational and dielectric properties and to issue recommendations for creating coatings based on them for protection of the transportation vehicle’s parts.
