Polymorphism of self-assembled colloidal nanostructures of comblike and bottlebrush block copolymers
Résumé
Block copolymers comprising chemically different comblike or bottlebrush blocks can self-assemble in selective solvents giving rise to spherical or wormlike micelles or to polymersomes. The self-consistent field theoretical framework is used for predicting relation between the set of architectural parameters of the blocks (polymerization degrees of the main and side chains, density of grafting of the side chains to the backbone) and structural properties and morphology of the self-assembled aggregates. In particular, it is demonstrated that replacing linear blocks by architecturally symmetrical bottlebrush ones allows tuning the morphology of the self-assembled solution nanostructures.
