Ultradense Polymer Brushes by Adsorption
Angewandte Chemie, 2009AbstractVollgepackte Stehplatzränge: Dichte Polymerbürsten entstehen durch Anlagerung von Diblockcopolymeren mit einem neutralen und einem Polyelektrolyt‐Block an entgegengesetzt geladene Polyelektrolytbürsten (siehe Bild). Die Dichte der resultierenden neutralen Bürsten wird bestimmt durch die Ladungskompensation und kann 1 nm−2 übersteigen.

Shear-Stable Polymer Brush Surfaces
Langmuir, 2022Research on polymer brushes (PBs) has aroused great interest due to their wide range of applications in lubrication, antifogging, antifouling, self-cleaning, antiadhesion, antibacterial effects, and so forth. However, the weak mechanical strength, especially the low bond strength between the PBs and the substrate surface, is a long-standing challenge ...

Semiflexible polymer brushes and the brush-mushroom crossover
Soft Matter, 2015Semiflexible polymers end-grafted to a repulsive planar substrate under good solvent conditions are studied by scaling arguments, computer simulations, and self-consistent field theory. Varying the chain length N, persistence length lp, and grafting density σg, the chain linear dimensions and distribution functions of all monomers and of the free chain

We investigate the properties of polymer brushes made of symmetric and asymmetric starlike polymers in good solvent using Langevin dynamics simulations. Two types of populations coexist in such a brush, one of them being made of highly stretched polymers and a second one made of stars that are retracted inside the lower brush regions.

A polymer brush can be defined as a dense array of polymers end-attached to an interface that stretch out into the surrounding medium. Polymer brushes have been investigated for the past 30 years and have shown to be an extremely useful tool to control interfacial properties. This review is intended as an introduction into this very vibrant and diverse

Polymer brushes––surface immobilized polymers
Surface Science, 2004The synthesis of tethered block copolymer brushes via the use of controlled/living free radical polymerization techniques presents many significant advantages over traditional free radical polymerization techniques. In our group, we have found that the most versatile controlled/living free radical polymerization techniques are atom transfer radical ...

Advanced Functional Materials, 2013
AbstractThe charge storage properties of polymer brushes are reported for the first time. Poly(methyl methacrylate) (PMMA) brushes are explored as electrets to store electrostatic charges. Micrometer‐ and nanometer‐scale patterns of electrostatic charges are successfully fabricated on planar and non‐planar PMMA brush films by means of conductive ...

Polymer Brushes for Surface Tuning
Macromolecular Rapid Communications, 2009AbstractMixed polymer brushes as functional ultra thin films for surface functionalization have an enormous potential to create a variety of smart, switchable, and multifunctional surfaces and thin films. It is shown how computer simulations can contribute to a better understanding of the switching behavior of brushes.

Binary Polymer Brushes of Strongly Immiscible Polymers
ACS Applied Materials & Interfaces, 2015The phenomenon of microphase separation is an example of self-assembly in soft matter and has been observed in block copolymers (BCPs) and similar materials (i.e., supramolecular assemblies (SMAs) and homo/block copolymer blends (HBCs)). In this study, we use microphase separation to construct responsive polymer brushes that collapse to generate ...
