Nanofibrillar micelles and entrapped vesicles from biodegradable block copolymer/polyelectrolyte complexes in aqueous media

Polymerization induced self-assembly: an opportunity toward the self-assembly of polysaccharide-containing copolymers into high-order morphologies

Self-assembly of polysaccharide-containing amphiphilic copolymers: polymerization induced self-assembly versus traditional techniques.

Dual-responsive recurrent self-assembly of a supramolecular polymer based on the host–guest complexation interaction between β-cyclodextrin and azobenzene

A novel supramolecular polymer PAE-g-Azo@β-CD-PEG was constructed, which significantly displayed pH- and photo-dual-responsive recurrent self-assembly behaviors.

Regulation of the self-assembly morphology of azobenzene-bearing double hydrophobic block copolymers in aqueous solution by shifting the dynamic host–guest complexation

The complexation equilibrium between azo and β-CD can be shifted by various methods, thus the micellar morphology of azo-bearing block copolymers is altered.

Large compound vesicles from amphiphilic block copolymer/rigid-rod conjugated polymer complexes

Morphology evolution in complexes of amphiphilic block copolymers poly(styrene)-b-poly(acrylic acid) (PS-b-PAA) and poly(styrene)-b-poly(ethylene oxide) (PS-b-PEO) in the presence of polyaniline (PANI) in aqueous solution is reported. Transmission electron microscopy, atomic force microscopy, and dynamic light scattering techniques were used to study the morphologies at various PANI contents [aniline]/[acrylic acid] ([ANI]/[AA]) ranging from 0.1 to 0.7. The interpolyelectrolyte complex formed between PAA and PANI plays a key role in the morphology transformation. Spherical micelles formed from pure block copolymers were transformed into large compound vesicles upon increasing PANI concentration due to internal block copolymer segregation. In addition to varying PANI content, the kinetic pathway of nanoparticle formation was controlled through different water addition methods and was critical in the formation of multigeometry nanoparticles.

Self-assembled multimicellar vesicles via complexation of a rigid conjugated polymer with an amphiphilic block copolymer

We report here a facile method for fabrication of multimicellar vesicles from self-assembled complexes of a flexible coil-like block copolymer and a rigid rod conjugated homopolymer.
