Self-assembly of Amphiphilic Graft Copolymer in Selective Solvent

doi:10.7503/cjcu20120716

Abstract

Abstract:

The self-assembly of amphiphilic graft copolymer in different selective solvent was studied by coarse-grained molecular dynamics(CGMD) simulations. Influence of the rigidity of the backbone chain is mainly focused on. The results show that, when the solvent is good for the backbone while bad for the branches, flower micelle, flower-bridge micelle and bridge micelle can be obtained by increasing the rigidity of the backbone, when the solvent is bad for the backbone while good for the branches, core-shell structure with spherical or ellipsoidal shape, as well as the bunch structure, can be observed. Only the single core-shell structure can be obtained even for long chains in this selective solvent.

Key words: Amphiphilic graft copolymer, Self-assembly, Selective solvent, Flower micelle, Bridge micelle, Core-shell micelle
