A brush-like structure emerges from the stretching of long polymer chains, densely grafted on to the surface of an impermeable substrate. This structure is due to a competition between the

Stress in a Stimuli-Responsive Polymer Brush

The application of a polymer brush in sensing, actuation, self-folding, among others acutely depends on the tuneable bending of a brush-grafted substrate caused by the stress in the brush. However,

Tuning thermal conductivity of surface-initiated polymer brushes

Surface-initiated polymer brushes are widely used in industrial applications owing to their programmable interfacial properties and manipulation over the harmonious combination of materials at the



Finite extensibility and density saturation effects in the polymer brush

We study the equilibrium statistics of flexible neutral polymer chains attached by one end onto a flat interface (the polymer « brush »). We account for the finite extensibility of the polymers,

Static and dynamic properties of polymer brushes at moderate and high grafting densities: A molecular dynamics study

We study static and dynamic properties of polymer brushes of moderate and high grafting densities using molecular dynamics simulations. The self-consistent-field theory is able to reproduce the

A new numerical approach to dense polymer brushes and surface instabilities.

A numerical self-consistent field (SCF) method which describes freely jointed chains of spherical monomers applied to densely grafted polymer brushes is presented and the obtained results are in very close agreement with corresponding MD simulations.

Polymer brushes in solvents of variable quality: molecular dynamics simulations using explicit solvent.

The structure and thermodynamic properties of a system of end-grafted flexible polymer chains grafted to a flat substrate and exposed to a solvent of variable quality are studied by molecular dynamics methods and the reduction of the surface tension between solvent and wall as a function of the grafting density of the brush is obtained.

Structure and dynamics of grafted polymer layers: A Monte Carlo simulation

The bond fluctuation model of polymer chains on lattices is used to study layers of polymers anchored with one end at a hard wall, assuming good solvent conditions and repulsive interactions between

Polymer brushes on flat and curved surfaces: How computer simulations can help to test theories and to interpret experiments

Theoretical descriptions of static properties of polymer brushes are reviewed, with an emphasis on monodisperse macromolecules grafted to planar, cylindrical, or spherical substrates. Blob concepts

Individual Polymer Paths and End-Point Stretching in Polymer Brushes

Molecular dynamics simulations and self-consistent field calculations have been used to study average polymer paths of end-grafted, strongly overlapping polymers in a good solvent. Contrary to what

Static properties of end-tethered polymers in good solution: a comparison between different models.

A comparison between results, obtained from different simulation models, for the static properties of end-tethered polymer layers in good solvent, shows that the data for the bond fluctuation and the Grest-Murat model can be analyzed in terms of scaling theory because chains are swollen inside the Pincus blob.
