Abstract
This chapter discusses the self assembly of block polyelectrolytes in which the insoluble blocks are relatively short; these form star-like spherical micelles with small, compact cores, and large, extended coronae. Several aspects of star-like micelles are described, including variations in critical micelle concentrations, micelles sizes, and the solubilization of organic molecules as functions of block copolymer and solution properties. The chapter describes the formation of crew-cut micelles from block polyelectrolytes with relatively long insoluble blocks. These aggregate molecules have large cores surrounded by a relatively thin shell of hydrophilic coronal chains. Detailed studies of spherical micelles, which form in certain ranges of block copolymer compositions, are also discussed in the chapter. The wide range of nonspherical morphologies has been observed in aqueous solutions of crew-cut aggregates.
