Values of the critical surface tension of the liquid (ethanol solution containing different amounts of water) on the boundary with the solid body (fraction of sandy soil with different dispersion) were calculated, using the method of Zisman. Greatly increased supply of surface free energy and the strengthening of inter-particle interaction with increasing of dispersion were established. Based on this research, were proposed to use a constant Hamaker and critical surface tension as a criteria for the formation and characteristics of the surface state of the dispersed material. This will allow us to estimate the strength of the relationship of composites based on nanostructures.
Используя метод Зисмана, рассчитаны значения критического поверхностного натяжения жидкости (растворы этанола с различным содержанием воды) на границе с твердым телом (фракции песчаного грунта с различной степенью дисперсности). Показано, что с увеличением степени дисперсности, значительно возрастает запас свободной поверхностной энергии и усиление межчастичного взаимодействия. На основании проведенного исследования, в качестве критериев процесса формирования и характеристики состояния поверхности дисперсного сырья предлагается использовать постоянную Гамакера и критическое значение поверхностного натяжения. Это позволит оценить силу взаимосвязи композитов на основе наноструктур.
