A polymer brush is a thin layer of polymer chains anchored at one end to a solid surface or interface, with the other ends extending into the surrounding medium, which can be a liquid or gas. This configuration creates a "brush-like" appearance, as the polymer chains protrude outward and can form a dense array. Polymer brushes are significant in various fields, including materials science, biology, and nanotechnology, due to their unique properties and functionalities.
