Thermally-induced transition of lamellae orientation in block-copolymer films on ‘neutral’ nanoparticle-coated substrates
Kevin G. Yager,Christopher Forrey,Gurpreet Singh,Sushil K. Satija,Kirt A. Page,Derek L. Patton,Jack F. Douglas,Ronald L. Jones,Alamgir Karim +8 more
TL;DR: It is found that both surface interactions and temperature play a crucial role in dictating block-copolymer lamellae orientation, and suggesting that controlling substrate roughness should provide a useful and robust platform for controlling block- Copolymer orientation in applications of these materials.

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.
