DIBLOCK COPOLYMER ADSORPTION ON SMALL PARTICLES

In this paper we use self-consistent field theory to study the adsorpt ion of diblock copolymers onto small colloidal particles. The particle s are modeled as spheres and the assumption is made that the adsorptio n parameter of the adsorbing segments is independent of the particle c urvature. We find that the adsorbed amount per unit of surface area in creases with increasing curvature. The hydrodynamic layer thickness de creases greatly with increasing curvature. The root-mean-square layer thickness does not vary much when the curvature changes.
