摘要

Abstract

The morphological changes of ABA amphiphilic triblock copolymer micelles in dilute solution were systematically studied by tuning the solvent property using self-consistent field simulation. The solvent property was tuned by changing the Flory-Huggins interaction parameters between each type of blocks and solvent

respectively. The simulation results show that by changing the solvent properties

a series of micelle morphologies such as vesicle

cage-like

ring-shaped

rod-like and spherical micelle morphologies can be obtained. Variations of the free energy of the solution system and the surface area of micelles with the Flory-Huggins interaction parameters were calculated to better understand the effect of solvent property on micelle morphologies. In addition

a phase diagram showing the morphological changes of micelles with the Flory-Huggins interaction parameters is provided.
