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.

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 ...

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.

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).

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 ...

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.

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.

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.

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.

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
