Polymer brush refers to a macromolecular assembly which is formed by polymer chains densely attached by one end to a surface or an interface.1,2 For a brush, the distance between neighboring grafting sites (D) is much smaller than the gyration radius (Rg) of free polymer chains (normally D should be at least smaller than 2Rg) so that the polymer chains stretch away from the interface into the solution.3 Since the report that grafting polymer molecules to colloidal particles was an effective way to prevent flocculation in the 1950s,4,5 polymer brushes have attracted considerable attention in protein immobilization,6 catalysis,7 nanoreactors,8 environmental engineering,9 disease diagnosis10,11 and other fields.12
