Multicompartment micelles have advanced applications in biological and pharmaceutical fields. The self-assembly of the block copolymers with different chain architectures provides versatile and powerful routes to obtain multicompartment micelles in water. Here we apply the dissipative particle dynamics method to study the self-assembly of H-shaped triblock copolymers in a selective solvent. It is found that the H-shaped triblock copolymers can form micelles with different morphologies, such as worm-like micelles, hamburger micelles, core-shell-corona micelles, and cylinder micelles, etc. Among them, the cylinder micelles have not been reported before in the case of the copolymers with similar chain architecture (e.g., Y-shaped copolymer). We demonstrate a convenient approach to obtain different morphologies by only adjusting the arrangement of the copolymers' blocks. These results may be helpful for the design of multicompartment micelles for various application purposes.

We investigated the interfacial properties of symmetric ternary An/AmBm/Bn and An/Am/2BmAm/2/Bn polymeric blends by means of dissipative particle dynamics (DPD) simulations. We systematically analyzed the effects of composition, chain length, and concentration of the copolymers on the interfacial tensions, interfacial widths, and the structures of each polymer component in the blends. Our simulations show that: (i) the efficiency of the copolymers in reducing the interfacial tension is highly dependent on their compositions. The triblock copolymers are more effective in reducing the interfacial tension compared to that of the diblock copolymers at the same chain length and concentration; (ii) the interfacial tension of the blends increases with increases in the triblock copolymer chain length, which indicates that the triblock copolymers with a shorter chain length exhibit a better performance as the compatibilizers compared to that of their counterparts with longer chain lengths; and (iii) elevating the triblock copolymer concentration can promote copolymer enrichment at the center of the interface, which enlarges the width of the phase interfaces and reduces the interfacial tension. These findings illustrate the correlations between the efficiency of copolymer compatibilizers and their detailed molecular parameters.
