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.

AbstractTriblock copolymers have traditionally been synthesized with conventional organic components. However, triblock copolymers could be synthesized by the incorporation of two incompatible protein-based polymers. The polypeptides would differ in their hydrophobicity and confer unique physiochemical properties to the resultant materials. One protein-based polymer, based on a sequence of native elastin, that has been utilized in the synthesis of biomaterials is poly (Valine-Proline-Glycine-ValineGlycine) or poly(VPGVG) [1]. This polypeptide has been shown to have an inverse temperature transition that can be adjusted by non-conservative amino acid substitutions in the fourth position [2]. By combining polypeptide blocks with different inverse temperature transition values due to hydrophobicity differences, we expect to produce amphiphilic polypeptides capable of self-assembly into hydrogels. Our research examines the design, synthesis and characterization of elastin-mimetic block copolymers as functional biomaterials. The methods that are used for the characterization include variable temperature 1D and 2D High-Resolution-NMR, cryo-High Resolutions Scanning Electron Microscopy and Differential Scanning Calorimetry.
