摘要：
A simple scaling model is presented for the polymeric core-shell nanostructure formed through the self-assembly of block copolymer poly(ethylene oxide)-b-poly(propylene oxide) in a selective solvent. The radius of the core (Rc) and the thickness of the shell can be scaled to the copolymer composition, such that Rc-1∝m/n and δ∝m2/3, where m and n are the numbers of the repeating units of the soluble and insoluble blocks in a AmBn or AmBnAm type block copolymers.
