摘要：

The adsorption energy of the surface-active disk-shaped J-beads at the liquid-liquid interfaces was studied. The estimated adsorption energy was found to be remarkably larger than that of the ordinary surfactants molecules. It was observed that the growth of solid-stabilized droplets is rather slow because their coalescence is supressed by the adsorbed powders. The adsorption of the spherical or the disk-shaped surface-active particles at liquid-liquid interfaces was found to be much stronger than that of ordinary surfactant molecules.
