New developments in polymer brush fabrication: concepts and …

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… WebDec 25, 2024 · Polymer brushes are commonly synthesized by two main approaches called “grafting from” and “grafting to”.
