“…[102] Two reviews on ionic block copolymers were published by Selb and Gallot [103] and Eisenberg and coworkers. [104] For all applications based on the micellar aggregates of ABCs, the aggregation number Z, i.e., the number of block copolymers in a micelle, and the related size of block copolymer micelles is an important parameter. Recently, it has been shown that a general relation of the form in Equation 1 holds for many diblock, triblock, and graft copolymers as well as for low molecular weight non-ionic, anionic, and cationic surfactants.…”

Amphiphilic block copolymers (ABCs) are important in interface and particle stabilization. Following consideration of the various methods of synthesis of ABCs, mesophases and micelles of block copolymers and the solubilization and adhesion of ABCs are considered. The Figure shows micelles formed by a polystyrene‐poly(vinylpyridine) copolymer. Nanoparticles and ABC/nanoparticle hybrid systems are also reviewed.

Free radical polymerization of N,N-(dimethylamino)ethyl methacrylate and N,N-dimethyl-N-(methacryloyloxy)ethyl ammonium butane sulfonate was carried out to prepare PDMAEMA and PDMABS. Proton nuclear magnetic resonance spectroscopy indicated that both PDMAEMA and PDMABS exhibited an electrolyte-responsive conformational dynamics in D 2 O of different ionic strength. PDMAEMA, as a polybase, and PDMABS, as a polysulfobetaine, exhibited a series of multidimensional stimuli-responsive phase transition behaviors. Adding NaCl would decrease the phase transition temperature (T PT ) of their aqueous mixtures, because of polyelectrolyte effect for PDMAEMA and anti-polyelectrolyte effect for PDMABS, respectively. For PDMAEMA, a low pH would facilitate the dissolution; on the other hand, for PDMABS, a maximum T PT was achieved in neutral media.

“…There have been no systematic explorations of this concept to date, although various studies are relevant. 22,23 The key step is to develop chemistry in which may be varied progressively but over a very large range. For example, values as large as 10 or 100 may be necessary.…”

Fluorinated block copolymers combine the unique properties of fluoropolymers and the intriguing self-assembly of hybrid macromolecules. The preparation of the title molecules by selective fluorination procedures and the effect of fluorine incorporation on the material thermodynamics are presented. We highlight two fluorination schemes developed in our laboratory, difluorocarbene and perfluoroalkyliodide additions to polydienes, that allow for the selective and tunable incorporation of different fluorinated groups into model block copolymers. The fluorination changes the physical properties of the parent materials and leads to interesting changes in the component incompatibilities. The role of fluorination in determining block copolymer thermodynamics in both the solid state and in solution and in ultimately exploiting fluorination to produce novel, higher order structures is central to our research efforts.
