文摘

A series of water-soluble hexa-armed cationic star polyelectrolytes and anionic star polyelectrolytes with a hexafunctional cyclotriphosphazene derivative core were synthesized. The self-assembly behaviors of these complementary star polyelectrolyte pairs in water in the effect of electrostatic interaction were investigated. It was found that the complementary star polyelectrolyte pairs system could form various morphologies such as fiber bundles and double wall vesicles in water by adjusting molecular weight, polymer concentration, the matching degree of star polyelectrolyte pairs, and the preparation conditions of the self-assembly solvents. The self-assembly mechanisms for the formation of nanofibers and double wall vesicles were discussed.
