摘要
In this paper, "star anise"-like anisotropic micelle ( AM) from direct aqueous self-assembly of poly( ethylene oxide)-block-poly(p-dioxanone) amphiphilic diblock copolymer is presented. By adding poly( ethylene imine) ( PEI), the AM shows morphological change from "star anise" to swollen sphere. The mechanism of PEI-triggered morphological transition involving complexation and weakening of crystallizability is revealed.
