The observation by transmission electron microscopy of six different stable aggregate morphologies is reported for the same family of highly asymmetric polystyrene-poly-(acrylic acid) block copolymers prepared in a low molecular weight solvent system. Four of the morphologies consist of spheres, rods, lamellae, and vesicles in aqueous solution, whereas the fifth consists of simple reverse micelle-like aggregates. The sixth consists of up to micrometer-size spheres in aqueous solution that have… 
Structures of “crew-cut” aggregates of polystyrene-b-poly(acrylic acid) diblock copolymers
“Crew-cut” aggregates of polystyrene-b-poly(acrylic acid) block copolymers can be prepared by dissolving the copolymers in N,N-dimethylformamide (DMF) and adding water to the solution to induce
Self-assembled aggregates of dendritic-linear copolymers: vesicles and microspheres
Owing to the peculiarity of its molecular architecture, dendritic-linear copolymer consisting of Percec type dendron molecules and a relatively stiff
Micellization and the Surface Hydrophobicity of Amphiphilic Poly(vinylphenol)-block- Polystyrene Block Copolymers
The self-assembly of PVPh-b-PS in different solvents was studied. Upon replacing toluene by THF asthe solvent, the morphology of the resulting aggregates change from core-shell spheres, rod-like
Multiple morphologies of the aggregates from self‐assembly of diblock copolymer with relatively long corona‐forming block in dilute aqueous solution
Reported here is self-assembly behavior in selective solvent of diblock copolymers with relatively long corona-forming block compared to core-forming block. Three diblock copolymers, poly(ethylene
"Raft" formation by two-dimensional self-assembly of block copolymer rod micelles in aqueous solution.
The hierarchical growth of lamellae from one-dimensional rod subunits, which had been formed from spherical assemblies, is novel and controllable in terms of product size and aspect ratio.
Self-assembly of linear-dendritic diblock copolymers: from nanofibers to polymersomes.
The membrane of the sheet-like aggregates, tubular micelles, and polymersomes was shown to have a bilayer structure, as revealed by cryo-TEM and UV illumination of the aqueous polymersome dispersion induced the formation of wrinkles in the vesicle membrane, thus showing that this type of polymeric aggregate is photoresponsive.
Self-assembly of monodisperse polymer microspheres from PPQ-b-PEG rod-coil block copolymers in selective solvents
Poly(phenylquinoline)-block-poly(ethylene glycol)(PPQ-b-PEG) rod-coil block copolymers possess the self-assembly behavior in selective solvents. The copolymers in the mixed solvents
Multicompartmental hollow micelles formed by linear ABC triblock copolymers in aqueous medium.
The phase separation of hydrophobic PS and PCL blocks, as well as the hydrophilic/hydrophobic balance, plays a crucial role on the self-assembly behaviors of an ABC triblock copolymer in aqueous media.
Multiple morphologies from a novel diblock copolymer containing dendronized polymethacrylate and linear poly(ethylene oxide)
A novel amphiphilic diblock copolymer, consisting of dendronized polymethacrylate-b-poly(ethylene oxide), was synthesized via atom transfer radical polymerization; from it, micellelike aggregates of


Structural Transitions from Spherical to Nonspherical Micelles in Blends of Poly(styrene-butadiene) Diblock Copolymer and Polystyrene Homopolymers
Blending of a block copolymer with a large amount of homopolymer can result in the formation of a micellar phase consisting of spherical domains of the aggregating copolymer block. We show that
Determination of the micelle architecture of polystyrene poly(4-vinylpyridine) block copolymers in dilute solution
Block copolymers consisting of polystyrene (PS) and poly(4-vinylpyridine) (4-PVP) with varying chain lengths are synthesised via anionic polymerisation. When these block copolymers are dissolved in
Micellar morphology in bulk styrene-core ionic diblock copolymers
Diblock ionomers consisting of a short polystyrene block and a long ionic segment of poly-(4-vinylpyridinium methyl iodide) or poly(cesium methacrylate) have been investigated by SAXS in the solid
Critical micelle lengths for ionic blocks in solutions of polystyrene-b-poly(sodium acrylate) ionomers
The micellar solutions of polystyrene-b-poly(sodium acrylate) ionomers in THF and NMP were investigated by SEC. Peaks were seen corresponding to both micelles and functionalized single chains; in
Complex Phase Behavior of Polyisoprene-Polystyrene Diblock Copolymers Near the Order-Disorder Transition
The phase behavior of polyisoprene-polystyrene (PI-PS) diblock copolymers near the order disorder transition was investigated using dynamic mechanical measurements, TEM, SAXS and SANS at polyisoprene
Block copolymer self‐assembly in selective solvents: Spherical micelles with segregated cores
A theory of micellization of AB diblock copolymer molecules in a selective solvent S is developed here. The micelles are assumed to have a completely segregated core region consisting only of the A
Disorder-order transitions in soft sphere polymer micelles.
The first phase diagram for block copolymer micelles is presented to include both bcc and fcc structures and characterize the lattice selection by a ratio of coronal layer thickness to core radius.
Spontaneous vesicle formation in aqueous mixtures of single-tailed surfactants.
Spontaneous, single-walled, equilibrium vesicles can be prepared from aqueous mixtures of simple, commercially available, single-tailed cationic and anionic surfactants. Vesicle size, surface charge,
