Nanostructured bio-functional polymer brushes
Journal of Biomaterials Science, Polymer Edition, 2006Structured poly(glycidyl methracrylate) (poly-GMA) brushes have been grafted onto flexible fluoro-polymer films using a radiation grafting process. The reactive epoxide of poly-GMA provides the basis for a versatile biofunctionalization of the grafted brushes. Structure definition by extreme ultraviolet (EUV) exposure allowed nanometer-scale resolution

Sliding Friction with Polymer Brushes
Physical Review Letters, 2003Using high-resolution shear force measurements, we examine in detail the frictional drag between rubbing surfaces bearing end-tethered polymeric surfactants (brushes). The drag attains a maximum on initial motion, attributed to elastic stretching of the chains, which falls by a cascade of relaxations to a value characteristic of kinetic friction.

Area Selective Polymer Brush Deposition
Macromolecular Rapid Communications, 2017Polymer brush films with chemical functionality to attach to site specific substrate areas are introduced for area selective deposition (ASD) application. It is demonstrated that polymer brushes with chemically defined end sites can be selectively bound to copper‐specific regions of patterned copper/silica (Cu/SiO2) substrates.

Journal of Macromolecular Science, Part C: Polymer Reviews, 2006
The review focuses on responsive/switching behavior of polymer brushes. The structure of the polymer brushes is analyzed in terms of the constitution and conformation of polymer chains. Responsive properties are widely discussed based on phase transition mechanisms in a controlled environment when changes are induced by solvent quality, temperature ...

Polymer brushes at curved surfaces
Macromolecules, 1993The polymer adsorption theory of Scheutjens and Fleer is used to describe polymer brushes at spherical and cylindrical surfaces that are immersed in a low molecular weight solvent. The volume fraction profiles of such brushes is analyzed, special attention being paid to spherical brushes in athermal solvents. These are shown to generally consist of two

Polymer Brushes: Promises and Challenges
Chemistry – An Asian Journal, 2013AbstractSurface‐tethered polymers, or “polymer brushes”, are emerging as key elements in the context of regulating the surface characteristics of materials. Their properties, such as biocompatibility, antifouling, colloidal stability, wettability, and corrosion resistance, play a vital role in ascertaining their potential applications. The availability

Chemistry One way to modify a surface and control or improve its properties is to grow polymer chains off the surface to form a "brush." One method for growing polymer brushes from surfaces—atom-transfer radical polymerization—can be controlled electrochemically, in that the process can be catalyzed by Cu+ ions but not by Cu2+. Li et al.
