Nanostructured Materials via the Pendant Self-Assembly of Amphiphilic Crystalline Random Copolymers.
TL;DR: Versatile self-assembly systems to nanostructured materials in both solid and solution were developed with common amphiphilic random copolymers bearing hydrophilic poly(ethylene glycol) (PEG) and hydrophobic crystalline octadecyl pendants, giving various thermoresponsive, compartmentalized materials in aqueous and organic media.

Highly asymmetric lamellar nanopatterns via block copolymer blends capable of hydrogen bonding.
TL;DR: This work presents a conceptually new and versatile approach to produce highly asymmetric lamellar morphologies by the use of binary blends of block copolymers whose components are capable of hydrogen bonding, and demonstrates that the strategy can be transferred to thin film morphologies.

Takashi Uemura,Tetsuya Kaseda,Yotaro Sasaki,Munehiro Inukai,Takaaki Toriyama,Atsushi Takahara,Hiroshi Jinnai,Hiroshi Jinnai,Susumu Kitagawa +8 more
TL;DR: A new protocol for the compatibilization of immiscible polymers at the molecular level using porous coordination polymers (PCPs) as removable templates is described, which results in a PSt/PMMA blend that is homogeneous in the range of several nanometers.

Controlling the orientation of block copolymer thin films using thermally-stable gold nanoparticles with tuned surface chemistry
Misang Yoo,Seyong Kim,Se Gyu Jang,Soo-Hyung Choi,Hyunseung Yang,Edward J. Kramer,Won Bo Lee,Bumjoon J. Kim,Joona Bang +8 more
TL;DR: In this paper, the authors developed a novel strategy to control the orientation of microdomains in block copolymer thin films by introducing either selective or neutral gold nanoparticles (Au NPs) that were thermally stable.

Ordered mesoporous molecular sieves synthesized by a liquid-crystal template mechanism
TL;DR: In this paper, the synthesis of mesoporous inorganic solids from calcination of aluminosilicate gels in the presence of surfactants is described, in which the silicate material forms inorganic walls between ordered surfactant micelles.

Block Copolymer Thermodynamics: Theory and Experiment
TL;DR: Block copolymers are macromolecules composed of sequences, or blocks, of chemically distinct repeat units that make possible the sequential addition of monomers to various carbanion-ter minated ("living") linear polymer chains.

Block Copolymers—Designer Soft Materials
TL;DR: The Knitting Pattern as mentioned in this paper is a block copolymer that was discovered by Reimund Stadler and his coworkers and reflects a delicate free-energy minimization that is common to all blockcopolymer materials.
