Chemical Society Reviews, 2012 This critical review summarizes recent developments in the fabrication of patterned polymer brushes. As top-down lithography reaches the length scale of a single macromolecule, the combination with the bottom-up synthesis of polymer brushes by surface-initiated polymerization becomes one main avenue to design new materials for nanotechnology.

Strongly Charged Polymer Brushes [PDF]
Europhysics Letters (EPL), 2005 Charged polymer brushes are layers of surface-tethered chains. Experimental systems are frequently strongly charged. Here we calculate phase diagrams for such brushes in terms of salt concentration n_s, grafting density and polymer backbone charge ...

Friction between Ring Polymer Brushes [PDF]
Soft Matter, 2015 Friction between ring-polymer brushes at melt densities sliding past each other are studied using extensive course-grained molecular dynamics simulations and scaling arguments, and the results are compared to the friction between linear-polymer brushes ...

Supramolecular Polymer Brushes. [PDF]
ACS Polym Au, 2023 Polymer brushes are thin polymer films that consist of densely grafted, chain-end tethered polymers. These thin polymer films can be produced either by anchoring presynthesized chain-end functional polymers to the surface of interest ("grafting to"), or by using appropriately modified surfaces to facilitate growth of polymer chains from the substrate ("

Polymer brush hypersurface photolithography [PDF]
Nature Communications, 2020 AbstractPolymer brush patterns have a central role in established and emerging research disciplines, from microarrays and smart surfaces to tissue engineering. The properties of these patterned surfaces are dependent on monomer composition, polymer height, and brush distribution across the surface. No current lithographic method, however, is capable of

Polymer brushes Architecture on the modified surfaces [PDF]
مجلة جامعة الانبار للعلوم الصرفةIn last few decades, extensive research has been performed designing new synthetic procedures not only to create new classes of polymers, but also to control the architecture of those polymers. In order to improve the biocompatibility of medical implants

Atomic Force Microscopy of Polymer Brushes: Insights into Controversies
Frontiers in Mechanical Engineering, 2022 Atomic force microscopes (AFM) and nanoindenters have been used for decades to evaluate mechanical properties of thin films at the nanoscale. It is argued that the elastic solutions to the indentation problem, which are most often associated with the ...

Modeling lower critical solution temperature behavior of associating polymer brushes with classical density functional theory [PDF]
, 2013 We study the lower critical solution temperature (LCST) behavior of associating polymer brushes (i.e., poly(N-isopropylacrylamide)) using classical density functional theory.
