摘要
Amphiphilic triblock copolymers (PEOx-b-PDMSy-b-PEOx) 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.
