Interaction Between the Bimodal Micelles Self-assembled by PS-b-PAA and PS-b-PAPMA

Abstract

Abstract: The interaction between the binary micelles self-assembled by polystyrene-block-poly(acrylic acid) (PS-b-PAA) and polystyrene-block-poly(amino propylene-glycol methacrylate) (PS-b-PAPMA) in water was discussed in this paper. The results show the interaction between the binary micelles under a suitable condition results in the formation of a kind of special micelles called half-bred micelles through polymer chain exchanging between PS-b-PAA micelles and PS-b-PAPMA in water. A possible mechanism of chain exchanging is suggested for formation of the half-bred micelles.

Key words: Self-assembly, Half-bred micelles, Chain exchanging, PS-b-PAA, PS-b-PAPMA
