Self-assembly of a binary mixture of particles and diblock copolymers.
Using theoretical models, we undertake the first investigation into the synergy and rich phase behavior that emerges when binary particle mixtures are blended with microphase-separating copolymers. We isolate an example of spontaneous hierarchical self-assembly in such hybrid materials, where the system exhibits both nanoscopic ordering of the particles and macroscopic phase transformation in t...
متن کاملA theoretical and simulation study of the self-assembly of a binary blend of diblock copolymers.
Pure diblock copolymer melts exhibit a narrow range of conditions at which bicontinuous and cocontinuous phases are stable; such conditions and the morphology of such phases can be tuned by the use of additives. In this work, we have studied a bidisperse system of diblock copolymers using theory and simulation. In particular, we elucidated how a short, lamellar-forming diblock copolymer modifie...
متن کاملTwo-dimensional self-assembly in diblock copolymers.
Diblock copolymers confined to a two-dimensional surface may produce uniform features of macromolecular dimensions (approximately 10-100 nm). We present a mathematical model for nanoscale pattern formation in such polymers that captures the dynamic evolution of a solution of poly(styrene)-b-poly(ethylene oxide), PS-b-PEO, in solvent at an air-water interface. The model has no fitting parameters...
متن کاملStriped, ellipsoidal particles by controlled assembly of diblock copolymers.
Control of interfacial interactions leads to a dramatic change in shape and morphology for particles based on poly(styrene-b-2-vinylpyridine) diblock copolymers. Key to these changes is the addition of Au-based surfactant nanoparticles (SNPs) which are adsorbed at the interface between block copolymer-containing emulsion droplets and the surrounding amphiphilic surfactant to afford asymmetric, ...
متن کاملSynthesis and Self-Assembly of Brush-Rod Diblock Copolymers in the Mixed Solvent of THF/H2O
Two amphiphilic brush-rod block copolymers, PEGMA37-b-MBPS87 and PEGMA37-b-MBPS141, were synthesized via ATRP of poly(ethylene glycol)monomethyl ether methacrylate (PEGMA) and (þ)-2,5-bis[40-((S)-2-methylbutoxy)phenyl]styrene (MBPS). The self-assembly of the copolymers in THF/H2O was induced by different methods. Spheres were dominant morphologies of PEGMA37-b-MBPS87 regardless of the initial c...
