摘要：
(Figure Presented) ABC gel: The triblock copolymer PS-b-P2VP-b-PEO undergoes simultaneous micellization and gelation, leading to high-storage-modulus materials that have fast responses to pH value, temperature, ionic strength, and shearing. The gel has a hierarchical structure (see picture) with spherical core-shell-corona micelles, which, in turn, pack closely into an ordered cubic structure. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
