Dissipative particle dynamics for directed self-assembly of block copolymers by Huang, Hejin, Alexander-Katz, Alfredo

“…In particular, it has been used to study block copolymer (BCP) self-assembly. However, previous parameterizations of this model are not able to capture most of the rich phase behaviors of BCPs in thin films nor in directed self-assembly (chemoepitaxy or graphoepitaxy). …”

Vertical Lamellae Formed by Two-Step Annealing of a Rod-Coil Liquid Crystalline Block Copolymer Thin Film by Lee, Sangho, Cheng, Li-Chen, Ross, Caroline A.

“…Here, we describe a two-step annealing method to produce vertically aligned lamellar structures in thin film of a silicon-containing rod-coil thermotropic liquid crystalline block copolymer. The rod-coil block copolymer with the volume fraction of the Si-containing block of 0.22 presents an asymmetrical lamellar structure in which the rod block forms a hexatic columnar nematic liquid crystalline phase. …”

Control of hierarchical polymer mechanics with bioinspired metal-coordination dynamics by Mozhdehi, Davoud, Cheng, Jing, Barrett, Devin G., Guan, Zhibin, Messersmith, Phillip B., Grindy, Scott Charles, Learsch, Robert W., Holten-Andersen, Niels

“…In conventional polymer materials, mechanical performance is traditionally engineered via material structure, using motifs such as polymer molecular weight, polymer branching, or block copolymer design. Here, by means of a model system of 4-arm poly(ethylene glycol) hydrogels crosslinked with multiple, kinetically distinct dynamic metal-ligand coordinate complexes, we show that polymer materials with decoupled spatial structure and mechanical performance can be designed. …”
