Влияние излучений на структуру и морфологию тонкопленочных фторсодержащих покрытий

Abstract

В работе приведены результаты теоретических и экспериментальных исследований создания наноструктурированных тонкослойных покрытий, сформированных на базе фторсодержащих олигомеров в зависимости от технологических параметров получения (вида энергетического воздействия, дозы излучения). Показано, что совмещение в одном технологическом цикле нескольких операций (активация поверхности, модифицирование тонкопленочного покрытия), значительно ускоряет процессы структурообразования в покрытии, что значительно усиливает процессы энергопереноса = The paper presents the results of theoretical and experimental studies on the creation of nanostructured thin-layer coatings formed on the basis of fluorine-containing oligomers, depending on technological production parameters (the type of energy impact, radiation dose). It is shown that the combination of several operations in one technological cycle (activation of the surface, modification of the thin-film coating) significantly accelerates the processes of structure formation in the coating, which significantly enhances energy transfer processes. Studies have shown that the energy impact on coatings of fluorine-containing oligomers has a common mechanism, but it is necessary to take into account the magnitude of the energy impact, the activity of the coating and the substrate on which the coatings are formed. A synergistic combination of these factors affects the intensity of structural changes in the coating, which predetermines the physical, chemical, and mechanical characteristics of the system. The process of influence of energy factors on the structure and properties of thin-film coatings from fluorine-containing oligomers formed on metal substrates was studied. The influence of technological factors (temperature, microwave soft X-ray radiation) on the structure of coatings formed on nonmetallic substrates from fluorine-containing oligomers promotes the formation of spherulitic supramolecular structures. As a result of this action, boundary layers are formed with minimal mobility of macromolecules. With an increase in the thickness of the coating and the dose of energy, the orientational effect of the solid substrate decreases, and the supramolecular structures exert a predominant influence on the structure and properties of the films
