Rigid sphere transport through a colloidal gas-liquid interface

Abstract:

In this paper we report on the gravity-driven transport of rigid spheres of various sizes through the fluid-fluid interface of a demixed colloid-polymer mixture. Three consecutive stages can be distinguished: (i) the sphere approaches the interface by sedimenting through the polymer-rich phase, (ii) it is subsequently transported to the colloid-rich phase and (iii) it moves away from the interface. The spheres are covered by a thin wetting film of the colloidrich phase, to which they are even...
