Innovative materials and technologies in functional engineering systems

Collective monograph highlights the results of systematic scientific research devoted to some innovative technological solutions in materials science. The practical application of the results of these studies covers electronic equipment, light industry, construction, and rocketry. Chapter 1 examines the problem of obtaining radiation-protective coatings based on epoxy composites for electronic equipment materials. Dependences of the electron concentration, specific conductivity, and Hall EMF on the induction of external magnetic field for the n-Si and n-Ge single crystals, irradiated by the fast electrons, coated with a layer of ED-20 epoxy resin, have been obtained. The composite layer was without fillers and with iron and aluminum powders as fillers. It has been shown that the presence of such a coating layer increases the radiation resistance of n-Si and n-Ge single crystals, and the greatest radiation resistance is achieved by silicon and germanium single crystals coated with an epoxy composite with an iron powder filler. The determined presence of the residual magnetization of the iron powder filler and the corresponding induced additional Hall EMF may be of practical importance in the development of energy storage systems based on irradiated n-Ge and n-Si single crystals covered with a layer of epoxy resin with iron powder filler. Chapter 2 is devoted to the development of nanopigments based on modified montmorillonite for the formation of polymer-mineral decoration of natural leather. An algorithm for obtaining nanopigments by successive modification of aqueous dispersions of montmorillonite with cationically active and anionically active compounds has been proposed. The composition of coating compositions with the use of nanopigments has been optimized and rational ratios of the components of the coating composition have been obtained, which ensure the formation of a polymer-mineral coating with the required level of operational properties. It has been proven that the use of nanopigments in the composition of coating compositions allows to reduce the consumption of coating paint for decoration, the thickness of the coating film and to obtain a coating with high quality indicators in terms of adhesion to dry and wet skin, resistance of the coating to multiple bends, dry and wet friction. Chapter 3 analyzes the modern level of the technology of coating processes on a vertical surface, which actualizes the study of the problem of improving the operati
