WebNov 29, 2024 · For example, “grafting-from” methods can tailor the surface properties by using polymer brushes—thin polymer films in which polymer backbones are tethered to a solid interface by one chain end ( 1 ). Chemical strategies can pattern surfaces at molecular and macromolecular levels, but precise fabrication of nanopatterned surfaces that bear ... A polymer brush is the name given to a surface coating consisting of polymers tethered to a surface. The brush may be either in a solvated state, where the tethered polymer layer consists of polymer and solvent, or in a melt state, where the tethered chains completely fill up the space available. These polymer layers can be tethered to flat substrates such as silicon wafers, or highly curved substrates such as nanoparticles. Also, polymers can be tethered in high density to anoth…
