Novel water-soluble micellar interpolyelectrolyte complexes
Article Abstract:
Turbidimetry, analytical ultracentrifugation, and fluorescence spectroscopy were used to examine the interaction of polyisobutylene-block-poly(sodium methacrylate) diblock copolymer micelles with a strong cationic polyelectrolyte, poly(N-ethyl-4-vinylpyridinium bromide), in alkaline media. It was observed that the diblock copolymer micelles and the cationic polyelectrolyte form peculiar water-soluble micellar complex species.

Colloidal complexes obtained from charged block copolymers and surfactants: a comparison between small-angle neutron scattering, cryo-TEM, and simulations
Article Abstract:
Small-angle neutron scattering and cryo-transmission electron microscopy of complexes made from polyelectrolyte-neutral block copolymers and surfactants are reported. Two block copolymer/surfactant systems are investigated and it is found that the core is constituted from densely packed surfactant micelles, presumably connected by the polyelectrolyte chains.

Comments on the scaling behavior of flexible polyelectrolytes within the Debye-Huckel approximation
Article Abstract:
The conformational behavior of flexible polyelectrolytes with electrostatic interactions described by the Debye-Huckel approximation is debated. It is suggested that more than one parameter is required to describe the internal chain behavior that is characterized by short-range flexibility and long-range stiffness.
