Block Copolymer at Nano-Patterned Surfaces

, 2012
We present numerical calculations of lamellar phases of block copolymers at patterned surfaces. We model symmetric di-block copolymer films forming lamellar phases and the effect of geometrical and chemical surface patterning on the alignment and ...

Well-defined donor-acceptor rod-coil diblock copolymers based on P3HT containing C-60: the morphology and role as a surfactant in bulk-heterojunction solar cells [PDF]

, 2014
The synthesis of well-defined rod-coil block copolymers consisting of P3HT donor and C-60 acceptor chromophores (P3HT-b-P(S(x)A(y))-C-60) in a molecular architecture is reported for use in bulk-heterojunction (BHJ) solar cells.

What Do Large Language Models Know About Materials?

Advanced Engineering Materials, EarlyView.
If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

Effect of crystallization of the polyhedral oligomeric silsesquioxane block on self-assembly in hybrid organic-inorganic block copolymers with salt

Giant, 2021
We present a DSC and X-ray scattering study investigating the effect of polyhedral oligomeric silsesquioxane (POSS) block crystallinity on the self-assembly of a poly(acryloisobutyl polyhedral oligomeric silsesquioxane)-b-poly(ethylene oxide)-b-poly ...

Easy orientation of diblock copolymers on self-assembled monolayers using UV irradiation

, 2009
A simple method based on UV/ozone treatment is proposed to control the surface energy of dense grafted silane layers for orientating block copolymer mesophases. Our method allows one to tune the surface energy down to a fraction of a mN/m.
