Polymer brush effect
WebMay 31, 2024 · The polymer brush normally swells in a good solvent, while it collapses in a poor solvent. An abnormal response of polymer brush, so-called co-nonsolvency, is a phenomenon where the brush collapses counter-intuitively in a good solvent mixture. In this work, the structural properties of the co-nonsolvency in the grafted polymers are … WebApr 8, 2024 · The brush density of a polystyrene brush in cyclohexane solvent is predicted using the equation of motion and demonstrates qualitative agreement with experimental density profiles. The Flory-Huggins parameter chosen to describe brush-solvent interactions affects the solvent distribution in the brush but has minimal impact on the brush density.

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 23, 2024 · Polymer brushes, coatings consisting of densely grafted macromolecules, have been known to experience an intrinsic lateral compressive stress, originating from …
