С применением ИК-спектроскопии, дериватографии, сканирующей электронной микроскопии и ξ-метрии исследован механизм взаимодействия тетраэтоксисилана с поверхностью указанных порошков и их морфология. Для всех модифицированных таким образом порошков характерно негомогенное распределение частиц с различными уровнями агрегации: преимущественно микрометрическая популяция частиц (кизельгур), образование микрометрического размера в сочетании с нанокластерами (аэросил, диоксид титана). Разбавленные суспензии функционализированных порошков во фторированном лаке были использованы для гидрофобизации поверхностей стекла, алюминия и стали. Наиболее высокое значение краевого угла смачивания водой (156о ) наблюдалось для покрытий по алюминию, полученных с использованием композиции, содержащей функционализированный аэросил.</p></abstract><trans-abstract xml:lang="en"><p>The conditions for functionalization of micro- and nanopowders of aerosil, titanium dioxide and diatomaceous earth by wetting them with a liquid hydrophobic agent (tetraethoxysilane) and giving them fobno/philic properties are investigated. Using infrared spectroscopy, derivatography, scanning electron microscopy, and ξ-metry, the mechanism of tetraethoxysilane interaction with the surface of these powders and their morphology were studied. All powders thus modified are characterized by a non-homogeneous distribution of particles with different aggregation levels: predominantly micrometer-sized particle population (diatomaceous earth), micrometer-sized formation combined with nanoclusters (aerosil, titanium dioxide). Diluted suspensions of functionalized powders in fluorinated varnish were used for hydrophobization of glass, aluminum, and steel surfaces. The highest value of the water wetting edge angle (156°) was observed for aluminum coatings obtained using a composition containing functionalized aerosil.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>функционализация</kwd><kwd>гидрофобные свойства</kwd><kwd>аэросил</kwd><kwd>диоксид титана</kwd><kwd>кизельгур</kwd><kwd>тетраэтоксисилан</kwd><kwd>смачивание</kwd><kwd>морфология</kwd><kwd>краевой угол смачивания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>functionalization</kwd><kwd>hydrophobic properties</kwd><kwd>aerosil</kwd><kwd>titanium dioxide</kwd><kwd>diatomaceous earth</kwd><kwd>tetraethoxysilane</kwd><kwd>wetting</kwd><kwd>morphology</kwd><kwd>edge wetting angle</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке БРФФИ (проект № Х22-018. № государственной регистрации 20221090).</funding-statement><funding-statement xml:lang="en">The work was carried out with the financial support of the Belarusian Republican Foundation for Basic Research (project № X22-018, grant № 20221090).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Superliquid-repellent surfaces prepared by colloidal silica nanoparticles covered with fluoroalkyl groups / M.
