Simultaneous fabrication of line and dot dual nanopatterns using miktoarm block copolymer with photocleavable linker

open access: yesNature Communications, 2017
Block copolymers that form nanodomains and are used in nanolithography usually do not form nanopatterns with multiple shapes. Here the authors report a block copolymer that allows for UV- induced cleavage of one arm and demonstrate the transformation of ...

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.

Mesoscale Block Copolymers

open access: yesAdvanced Materials, 2018
AbstractMaterials composed of well‐defined mesoscale building blocks are ubiquitous in nature, with noted ability to assemble into hierarchical structures possessing exceptional physical and mechanical properties. Fabrication of similar synthetic mesoscale structures will offer opportunities for precise conformational tuning toward advantageous bulk ...

Evaluation of graphene incorporation for mechanical properties of polypropylene composites [PDF]

open access: yesPolímeros
Graphene nanoparticles (GnP) were selected as an alternative reinforcing nanofillers, which enhances the mechanical properties of polypropylene (PP-homo and PP-block copolymer).

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.

Block Copolymer Nanocontainers

open access: yesACS Nano, 2010
Using cell dynamics computer simulation, we perform a systematic study of thin block copolymer films around a nanoparticle. Lamellar-, cylinder-, and sphere-forming block copolymers are investigated with respect to different film thicknesses, particle radii, and boundary conditions at the film interfaces.

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.

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.

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.
