In this study, we explore the fabrication of poly(2-isopropyl-2-oxazoline) brushes on macroscopic surfaces by exploiting the *grafting-to* approach. Firstly, carboxyl functionalized poly(2-isopropyl-2-oxazoline) molecules have been synthesized by ring opening cationic polymerization and subsequently, resulting polymer chains have been grafted onto the underlined substrates in brush-like conformation. A wide range of analytical tools including ellipsometry, contact angle, X-ray photoelectron spectroscopy, attenuated total reflection infrared spectroscopy and atomic force microscopy have been employed to characterize the polyoxazoline brushes. Finally, fabricated polymer brushes have been used to control adsorption of inorganic nanoparticles and protein molecules on macroscopic surfaces.
