Показано, что при низких температурах и, следовательно, невысоких скоростях коррозии цинкового (Zn) наполнителя для снижения пористости и создания условий для роста электроизоляционных свойств покрытия. целесообразно использование многослойной конструкции грунтовочного слоя. Активизация процесса самовосстановления в многослойных покрытиях может быть реализована при повышении температуры. Так, уже при 40°C модуль импеданса начинает расти во всем диапазоне частот. Фиксируется рост омической составляющей в высокочастотной (ВЧ) области при одновременном падении емкости и росте модуля угла диэлектрических потерь до 86°, что свидетельствует о повышении гидрофобности материала покрытия. Параллельно наблюдается активация протекторных свойств. Полученные результаты показывают, что оптимизация конструкции покрытия, в частности многослойность, в сочетании с ускорением в нем процессов внутренней диффузии и коррозии, позволяют придать покрытию «умные» свойства за счет реализации роста модуля импеданса и блокировки дефектов корродирующим металлическим дисперсным наполнителем при одновременном существенном продлении периода протекторной защиты.</p></abstract><trans-abstract xml:lang="en"><p>As part of the development of the concept of creating "smart" adaptive polymer anticorrosive coatings, the kinetics of electrochemical properties of thin- and thick-layer multilayer Zn-filled coatings at various temperatures from 23 to 60°C during prolonged exposure up to 150 days in 3% NaCl were studied. It is shown that at low temperatures and, consequently, low corrosion rates of zinc (Zn) filler, it is advisable to increase the thickness of highly filled composite coatings with active solid-phase additives in order to reduce porosity and create conditions for a restorative increase in impedance. Activation of the self-healing process in multilayer coatings can be realized with an increase in temperature. So already at 40°C, the impedance begins to grow over the entire frequency range. At the same time, an increase in the ohmic component in the high-frequency (HF) region is recorded, with a simultaneous drop in capacitance and an increase in the phase anglemodulus up to 86°, which indicates an increase in the hydrophobicity of the coating material. In parallel, the activation of tread properties is observed. The results obtained show that optimization of the coating design, in particular multilayering, combined with acceleration of coating’s internal diffusion and corrosion processes, make it possible to give the coating "smart" properties by implementing adaptive impedance growth and blocking defects with a corroding metal dispersed filler while significantly extending the period of antocorrosion protection.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электрохимический импеданс</kwd><kwd>полимерные покрытия</kwd><kwd>«умные» адаптивные покрытия</kwd><kwd>самовосстановление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electrochemical impedance spectroscopy</kwd><kwd>EIS</kwd><kwd>polymer coatings</kwd><kwd>"smart" adaptive coatings</kwd><kwd>self-healing coatings</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">A.
