Regulating depletion interaction between micelle and selective substrate

doi:10.7523/j.issn.2095-6134.2018.03.005

Abstract

Abstract: In this paper, self-consistent field theory is used to study the depletion interaction between spherical micelles and planar substrate induced by polymer solvents. In this system, diblock copolymers form micelles and homopolymer solvents act as depletion initiators. When the spherical micelle approaches the planar substrate, the depletion interaction will allow the micelle to be adsorbed near the substrate. The structure between the substrate and the bulk is controlled through adjusting the amplitude of the attractive interaction of the substrate, which results in the regulation of the depletion interaction.

Key words: depletion interaction, self-consistent field theory, micelle, substrate
