“…1(b)). 1–10 The nature of these self‐assembly behaviors in bulk or in solution depends primarily on the degree of polymerization ( N ), the interaction parameter ( χ ) and, most importantly, the volume fraction; the polydispersity, architecture, terminal functional units, common solvents, selective solvents, temperature and additives can also have influences 11–19 . Because the use of living polymerization to vary the volume fraction and the molecular weight of a block copolymer is generally synthetically complicated, the blending of block copolymers (e.g.…”

The self‐assembled structures formed through hydrogen bonding interaction of block copolymers in polymeric materials are interesting materials because of their potential applications in biomedicine, nanopatterning and photonics, taking advantage of their responsive and tunable properties. In this review, we discuss the self‐assembled nanostructures that can be obtained from hydrogen‐bonded diblock copolymer/homopolymer (A‐b‐B/C) and diblock copolymer (A‐b‐B/C‐b‐D) mixtures in the bulk and how these block copolymer mixtures can then be used to synthesize mesoporous silica, phenolic and carbon materials. © 2021 Society of Industrial Chemistry.

“…HPC has also been found for several copolymers synthesized for potential biological applications [40,41]. In that way, uracil-functionalized poly(3-caprolactone)-b-(4-vinylbenzyl uracil)s (PCL-b-PVBU) were synthesized for their bioinspired assembly forming different microstructures through nucleobase-induced supramolecular interactions [41].…”

“…Considered as one of the stable morphologies for asymmetric diblock copolymers, it has been found for many different copolymers [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52] as a result of their composition or by different annealing processes. In that way, for amphiphilic poly(4-di(9,9-dihexylfluoren-2-yl) styrene)-b-poly(2-vinylpyridine) (PStFl2m-b-P2VPn) [36] copolymer thin films self-assembled into different nanostructures as a function of copolymer block ratio and film preparation process: random two phases, horizontal hexagonal P2VP cylinders, and hexagonally close packed (HCP) P2VP spheres.…”

Due to the thermodynamic incompatibility between blocks, diblock copolymers can selfassemble in a wide variety of nanostructures, covalent linkage among blocks preventing the phase separation at macroscopic scale. Those nanostructures depend on copolymer composition (f), Flory-Huggins interaction parameter among both blocks (χ), and polymerization degree of the copolymer (N). Thin films of block copolymers can show different equilibrium morphologies such as spheres, cylinders, gyroids, and lamellas. Besides mentioned parameters, film preparation process (substrate, annealing process if any) and used solvent will determine self-assembled morphology. In the present review, the most important morphologies or microstructures obtained for different diblock copolymer films are presented, as well as the most important phase transitions among them. Different microstructures and the way in which they can be obtained become of great importance, as they could be used as templates for nanoparticle deposition, nanolithography, or nanopatterned materials with several potential applications in different fields such as nanoelectronics or nanomedicine.

“…The larger selective solvent content is necessary to change the interfacial free energy at a certain critical point; however, in this study we could not determine this value, even at 70 wt% MeCN content. 40 To observe the morphological change in the DMF/MeCN system, we turned to the PS 87 -b-PVBT 22 /A-PEO supramolecular complex in the DMF/ MeCN system because the higher molecular weight of the PS block would presumably increase the core-chain stretching and the interfacial tension between the solvent and the micellar core. As a result, we anticipated the possibility of observing a morphological change in the DMF/MeCN system.…”

In this study, we report a simple but effective method for preparing various multi-compartment micelle structures: poly(styrene-b-4-vinylbenzyl triazolylmethyl methylthymine) (PS-b-PVBT) diblock copolymers blended with the adenine-terminated poly(ethylene oxide) (A-PEO) homopolymer to obtain pseudo A-b-(B-g-C)-type terpolymers stabilized through thymine-adenine (T-A) multiple hydrogen bonding interactions between PVBT and A-PEO segments in DMF (N,N-dimethylformamide) common solvent after the addition of H 2 O or MeCN selective solvent. Transmission electron microscopy revealed several different multi-compartment micelle structures-raspberry-like spheres, core-shell-corona spheres, core-shell-corona cylinders, nanostructured vesicles, onion-like structures, segmented worm-like cylinders, and woodlouse-like structures-upon varying the molecular weight of the PS-b-PVBT block segments and the concentration of the selective solvent. Thus, we could induce changes in the multicompartment micelle structures, similar to those of ABC miktoarm star terpolymers, through simple blending of PS-b-PVBT block copolymers with an A-PEO homopolymer.
