A characteristic feature of the approach is the full consideration of hard-sphere molecular correlations according to the fundamental measure theory in the density functional method and finding the complete dependence of the grand thermodynamic potential of the system on stable droplet or bubble size. Although the obtained results show a qualitative agreement between the new calculated disjoining pressure dependences and those obtained by us earlier in the framework of a simpler gradient method of the molecular density functional, the new results differ significantly quantitatively. It is confirmed that the disjoining pressure in the liquid film around nanosized lyophilic particle grows with the particle radius and lyophilicity.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324596112">На основе выражения для большого термодинамического потенциала как функционала молекулярной плотности рассчитаны расклинивающие давления в тонких жидких пленках вокруг наноразмерных смачиваемых сферических частиц и в тонких паровых прослойках вокруг несмачиваемых частиц в зависимости от степени лиофильности, толщины пленок и размера частиц. Характерными особенностями расчета являются полный учет жесткосферных молекулярных корреляций по теории фундаментальной меры в методе функционала плотности и построение полной зависимости большого термодинамического потенциала системы от размера равновесной капли или пузырька. Хотя в работе показано качественное согласие рассчитанных зависимостей расклинивающего давления с полученными в рамках более простого градиентного метода функционала молекулярной плотности, новые результаты существенно отличаются количественно. Подтверждено, что расклинивающее давление в жидкой пленке вокруг наноразмерной лиофильной частицы растет с увеличением размера и лиофильности частицы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>thin film</kwd><kwd>vapor layer</kwd><kwd>lyophilicity</kwd><kwd>lyophobicity</kwd><kwd>wetting</kwd><kwd>disjoining pressure</kwd><kwd>density functional theory</kwd><kwd>fundamental measure theory</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тонкая пленка</kwd><kwd>паровая прослойка</kwd><kwd>лиофильность</kwd><kwd>лиофобность</kwd><kwd>смачивание</kwd><kwd>расклинивающее давление</kwd><kwd>метод функционала плотности</kwd><kwd>теория фундаментальной меры</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Дерягин Б.В., Чураев Н.В., Муллер В.М.
