Abstract

The structural changes occurring in oil layers during condensation of deuterated octane (C8D18) on the surface of a solid (single-crystal silicon) and a liquid (water solution with low (0.08 wt%) concentration of a non-ionic surfactant (C10E4)) have been studied by neutron reflectometry. The results demonstrate the presence of pseudo-partial wetting during condensation. The van der Waals attractive potential stabilizes a thin oil film coexisting with the residual droplet. We report a study of the growth dynamics of the residual droplet,
