Formation of giant polymer vesicles by simple double emulsification using block copolymers as the sole surfactant

نویسندگان

چکیده

Giant polymer vesicles are obtained from double emulsion droplets stabilized by low molecular weight block copolymers. The method is based on a simple two-step emulsification, with no additional surfactant required other than the copolymer.

Formation of polymer vesicles by simultaneous chain growth and self-assembly of amphiphilic block copolymers.

Polymerization-induced formation of amphiphilic diblock copolymer vesicles is performed in water at high concentrations by a single-step nitroxide-mediated controlled free-radical emulsion polymerization of 4-vinylpyridine, initiated by a water-soluble poly(sodium acrylate) macroalkoxyamine at alkaline pH.

Equilibrium emulsification of polymer blends by diblock copolymers

2014 The onset and morphology of various equilibrium emulsion phases for an A and B homopolymer mixture with diblock A-B copolymers as the compatibilizer, is investigated. Attention is focused on the relation between the relative lengths of the blocks and the elastic properties of the interfacial layer which determines the phase behavior. The curvature elastic moduli K and K, as well as the spo...

Asymmetric Hybrid Polymer–Lipid Giant Vesicles as Cell Membrane Mimics

Lipid membrane asymmetry plays an important role in cell function and activity, being for instance a relevant signal of its integrity. The development of artificial asymmetric membranes thus represents a key challenge. In this context, an emulsion-centrifugation method is developed to prepare giant vesicles with an asymmetric membrane composed of an inner monolayer of poly(butadiene)-b-poly(eth...

Crystal Design of Barium Sulfate using Double-Hydrophilic Block Copolymers.

Peach, peanut, fiber, and flower (see picture) crystal morphologies are achieved from the precipitation of simple minerals in the presence of specifically adsorbing polymers. These crystal design effects are illustrated using BaSO(4) and double-hydrophilic block copolymers, the latter featuring carboxylate, sulfonate, phosphonate, and aspartic acid groups.

Control of Barite Morphology by Double-Hydrophilic Block Copolymers

Barite particles with a rich variety of well-defined morphologies have been synthesized by using double-hydrophilic block copolymers (which consist of a hydrophilic solvating block and a hydrophilic binding block) as crystal growth modifiers to direct the controlled precipitation of barium sulfate from aqueous solution. The influences of variation in functional group and molecular structure of ...
