摘要: In this paper, we report on our recent findings concerning the structure of complex coacervate core micelles composed two types (complementary) block copolymers. Both copolymers have a polyelectrolyte (one cationic and other anionic) combined with neutral one. The opposite charges attract form close-to-electroneutral core. blocks corona micelles. Here, focus corona, which among possibilities assumes Janus configuration. Corresponding self-consistent field calculations confirm rich behaviour these systems. Unless solvent quality one chains is poor, do not expect an onion-like clear interface between layers. Disparities in chain length may only lead to gradual differences (local enrichments) radial distributions. case that both are good solvent, unfavourable mixing leads formation micelles, where occupy different hemispheres. separates regions exerts force core, will deform when surface tension too high. line experimental results, flattens like disk extend most direction poles.
