Summary: Amphiphilic triblock copolymers (PEO x ‐ b ‐PDMS y ‐ b ‐PEO x ) with different block lengths were synthesized and multi‐morphological complex crew‐cut, star‐like, and short‐chain aggregates were prepared by self‐assembly of the given copolymers. The morphologies and dimensions of the aggregates can be well controlled by variation of the preparation conditions. TEM, SEM, FFR‐TEM, and LLS studies show the resulting morphologies range from LCMs, unilamellar or multilayer vesicles, LCVs, porous spheres to nanorods.TEM images of the vesicles formed from PEO‐ b ‐PDMS‐ b ‐PEO.
