Hairy Particles Synthesized by Living Anionic Polymerization-induced Self-assembly and Evaluation of Their Nanostructure

Hairy particles consisting of polyisoprene-b-polystyrene (PI-b-PS) were synthesized by polymerization-induced self-assembly (PISA) based on a living anionic polymerization method. The molecular aggregation state of the hairy particles in wet condition was investigated in detail. The hairy particles in wet state formed core-shell structure with PS core radii of 8.6 nm and PI shell thickness of 4.1 nm. Hairy particles consisting of polyisoprene-b-polystyrene (PI-b-PS) were synthesized on the basis of living anionic polymerization-induced self-assembly. The particles were evaluated in wet and dry conditions using TEM, NMR, DLS and SAXS. The polymer particles in wet state formed core-shell structure with PS core radii of 8.6 nm and PI shell thickness of 4.1 nm.
