С применением ИК-спектроскопии, дериватографии, сканирующей электронной микроскопии и дзето-метрии исследованы механизм взаимодействия гидрофобных агентов с поверхностью указанных порошков и изменение их свойств в результате гидрофобизации. Суспензии функционализированных порошков во фторированном лаке использованы для гидрофобизации различных субстратов: стекла, алюминия, стали, тканей и бумаг. Наиболее высокое значение краевого угла смачивания водой (170°) было достигнуто для покрытий по алюминию, полученных с использованием композиции, содержащей функционализированный аэросил. Получены супергидрофобные покрытия на поверхности стали и стекле с краевым углом смачивания в диапазоне 150–165° и углом скатывания менее 10°, бумаги и ткани с объемной гидрофобностью (150–170°), сохраняющие это свойство в нормальных условиях эксплуатации не менее шести месяцев и при повышенной относительной влажности (более 80 %) не менее одного месяца.</p></abstract><trans-abstract xml:lang="en"><p>Conditions have been investigated and methodical techniques have been developed for functionalization of micro-, nanopowders of aerosil, titanium dioxide and diatomaceous earth based on vapor phase condensation of agents with low surface energy (tetraethoxysilane and stearic acid) in order to give them phobno/philic properties, as one of the requirements for creating materials or coatings with bulk superhydrophobicity Using IR spectroscopy, derivatography, scanning electron microscopy and x-metry, the mechanism of interaction of hydrophobic agents with the surface of the above powders and changes in their properties were investigated as a result of hydrophobization. Suspensions of functionalized powders in fluorinated lacquer were used for hydrophobization of various substrates: glass, aluminum, steel, fabrics and papers). The highest value of the marginal angle of wetting with water (170°) was achieved for coatings on aluminum obtained using a composition containing functionalized aerosil. Superhydrophobic coatings on the surface of steel, aluminum and glass with a marginal wetting angle in the range of 150–170° and a rolling angle of less than 10°, paper and fabric with volumetric hydrophobicity (150–170°) were obtained, retaining this property under normal operating conditions for at least 6 months and at elevated relative humidity (more than 80 %) for at least 1 month.</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>конденсация</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>condensation</kwd><kwd>morphology</kwd><kwd>wetting edge angle</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">Super-liquid-repellent surfaces prepared by colloidal silica nanoparticles covered with fluoroalkyl groups / M.
