Positron annihilation spectroscopy: a new frontier for understanding nanoparticle loaded polymer brushes [PDF]

open access: yes, 2015
Nanoparticle-loaded polymer brushes are powerful tools for the development of innovative devices. However, their characterization is challenging and arrays of different techniques are typically required to gain sufficient insight. Here we demonstrate for

Grafting photochromic spiropyran polymer brushes on natural rubber surface via surface-initiated ring-opening metathesis polymerization

open access: yesAlexandria Engineering Journal
The modification of stereoregulated functionalized polymers on the surface of natural rubber (NR) is a challenging task. This work provided a practicable grafting method to design photochromic polymer brushes on the NR surfaces using surface-initiated ...

Towards controlled polymer brushes via a self-assembly-assisted-grafting-to approach

open access: yesNature Communications, 2016
Polymer brushes, whereby single layers of polymers are tethered to surfaces, can be made by various methods but greater control over their fabrication is desirable.

The thickness of surface grafting layer on bio-materials directly mediates the immuno-reacitivity of macrophages in vitro

open access: yesOpen Life Sciences, 2020
Introducing the surface grafting layers to regulate bio-compatibility and bio-function is an important step in the tissue engineering field. However, whether the thickness variation of the introduced biomimetic layer impacts the behavior of the adhered ...

Conformational properties of polymer brushes with aggrecan-like macromolecules under strong stretching conditions on a cubic lattice

open access: yesНаучно-технический вестник информационных технологий, механики и оптики
The comb-like polymers are used to modify various surfaces due to their branched structure and a number of unique physical and chemical properties. With a sufficiently dense grafting, the macromolecules form a homogeneous polymer brush that completely ...

Signatures of a Concentration Dependent Flory chi Parameter: Swelling and Collapse of Coils and Brushes

open access: yes, 2002
The quality of solvents of polymers is often described in terms of the Flory chi parameter typically assumed to depend only on the temperature, T. In certain polymer-solvent systems fitting the experimental data enforces the replacement of chi(T) by a ...
