Именно для этих приложений особенно важно знать механизм распространения жидкости в нанопористых материалах и делать оценки временных характеристик отклика системы на высокоскоростные импульсные воздействия. Целью данной работы являлось исследование влияния скорости изменения давления в системе на процесс заполнения пор нанопористого материала несмачивающей жидкостью. Проведена серия экспериментов заполнения – вытекания в системе нанопористый материал (гидрофобизированный нанопористый силикагель Fluka 100 C8 (60759-50G) производства Sigma-Aldrich) – несмачивающая жидкость (деионизированная дистиллированная вода) при скоростях изменения внутреннего объема 0.24÷11.78 10‒2 см3/с при температуре 20 °С. На основе экспериментальных данных разработана методика определения скорости заполнения нанопористого материала несмачивающей жидкостью. Разработанная методика будет в дальнейшем использоваться для изучения заполнения нанопористых материалов несмачивающими жидкостями.</p></abstract><trans-abstract xml:lang="en"><p>The study of the interaction of a nanoporous material with a non-wetting liquid is of interest not only from the point of fundamental science view in terms of liquid distribution in nanochannels, but also as an application of such systems to absorb the energy of impact, explosion and vibrations. It is for these applications that it is especially important to know the mechanism of liquid distribution in nanoporous materials and to make estimates of the time characteristics of the system response to high-speed pulse effects. The purpose of this work was to study the effect of the rate of pressure change in the system on the process of filling the pores of a nanoporous material with a non-wetting liquid. A series of intrusion – extrusion experiments was carried out in the nanoporous material (hydrophobized nanoporous silica gel Fluka 100 C8 (60759-50G) by Sigma-Aldrich) – non-wetting liquid (deionized distilled water) system at internal volume change rates of 0.24 ÷ 11.78 10‒2 cc/s at a temperature of 20 °C. Based on experimental data, a method for determining the filling rate of a nanoporous material with a non-wetting liquid has been developed. The developed technique will be further used to study the filling of nanoporous materials with non-wetting liquids.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нанопористый материал</kwd><kwd>несмачивающая жидкость</kwd><kwd>нанофлюидика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nanoporous material</kwd><kwd>non-wetting liquid</kwd><kwd>nanofluidics.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 23-29-00352, https://rscf.ru/project/23-29-00352/.</funding-statement><funding-statement xml:lang="en">The study was supported by the Russian Science Foundation grant No. 23-29-00352, https://rscf.ru/project/23-29-00352/.</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">Majumder M. et al.
