Since surfaces and interfaces of soft materials play an important role in various technological applications, precise control of soft interfaces would greatly promote the innovation of materi-als science and technology. Hydrophilic polymers show unique functionality at various soft inter-faces. In this study, high-density hydrophilic polymer brushes nano-coatings were prepared on Si-wafer and various substrates by sur-face-initiated controlled radical polymeriza-tion. Chain conformation at liquid/solid liq-uid/solid interface was characterized by neutron reflectivity. Applications of polymer brushes as structural nano-coatings such as super hydro-philicity,antifouling behavior, and repeatable adhesion are presented.
