Abstract: A method is disclosed for preparing a patterned continuous polymeric brush on a substrate surface. The method generally involves functionalization of the substrate surface followed by surface-initiated polymerization at the initiation sites so provided, e.g., using a living free radical polymerization technique or the like, whereby a covalently bound continuous polymeric brush results, with acid-labile groups present throughout. An acid is then applied to the continuous polymer brush in a predetermined pattern, under conditions that result in removal of the acid-labile groups in at least one first region of the continuous polymer brush but not in at least one second region of the continuous polymer brush. In a preferred embodiment, the acid is a photogenerated acid resulting from imagewise irradiation of a photoacid generator applied as a film or coating to the surface-bound polymer brush.
