Ordering at two length scales in comb-coil diblock copolymers consisting of only two different monomers [PDF]

open access: yes, 2001
The microphase separated morphology of a melt of a specific class of comb-coil diblock copolymers, consisting of an AB comb block and a linear homopolymer A block, is analyzed in the weak segregation limit.

Stabilization of colloidal palladium particles by a block copolymer of polystyrene and a block containing amide sidegroups [PDF]

open access: yes, 1996
A block copolymer of polystyrene and poly(tert-butylmethacrylate) was prepared by anionic polymerization. The ester groups of the poly(tert-butylmethacrylate) were hydrolyzed, after wich the remaining carboxyl groups were reacted with pyrrolidine.

Origins of elastic properties in ordered nanocomposites [PDF]

open access: yes, 2004
We predict a diblock copolymer melt in the lamellar phase with added spherical nanoparticles that have an affinity for one block to have a lower tensile modulus than a pure diblock copolymer system.

Core-shell structures in single flexible-semiflexible block copolymers: Finding the free energy minimum for the folding transition [PDF]

open access: yes, 2007
We investigate the folding transition of a single diblock copolymer consisting of a semiflexible and a flexible block. We obtain a {\it Saturn-shaped} core-shell conformation in the folded state, in which the flexible block forms a core and the ...

Block copolymer self-assembly for nanophotonics [PDF]

open access: yes, 2015
The ability to control and modulate the interaction of light with matter is crucial to achieve desired optical properties including reflection, transmission, and selective polarization.

Mesoscale Simulations of pH-Responsive Amphiphilic Polymeric Micelles for Oral Drug Delivery

open access: yesPharmaceutics, 2019
It is of great significance to study the structure property and self-assembly of amphiphilic block copolymer in order to effectively and efficiently design and prepare drug delivery systems.

Synthesis and systematic optical investigation of selective area droplet epitaxy of InAs/InP quantum dots assisted by block copolymer lithography [PDF]

open access: yes, 2018
We report on the systematic investigation of the optical properties of a selectively grown quantum dot gain material assisted by block-copolymer lithography for potential applications in active optical devices operating in the wavelength range around 1 ...

Grain-Boundary-Induced Alignment of Block Copolymer Thin Films

open access: yesNanomaterials, 2020
We present and discuss the capability of grain boundaries to induce order in block copolymer thin films between horizontally and vertically assembled block copolymer grains.

Multipod structures of lamellae-forming diblock copolymers in three-dimensional confinement spaces: experimental observation and computer simulation [PDF]

open access: yes, 2016
The three-dimensional (3D) confinement effect on the microphase-separated structure of a diblock copolymer was investigated both experimentally and computationally.

Transient Optical Characterisation of Donor-Acceptor Block Copolymers for Use in Solar Cells [PDF]

open access: yes, 2010
This thesis presents a study of photo-active, semiconducting block copolymers for use in molecular solar cells. Current state-of-the-art organic devices utilise blends of two (or more) materials that are co-deposited from a common solution; the resulting
