Surfaces and interfaces play a critical role in many applications and devices1-3. Tuning hydrophilicity and hydrophobicity, tribology, adhesion and lubrication as well as antifouling characteristics of a surface is a fundamental requirement for the successful exploitation of forefront technologies ranging from optoelectronics to sensors and coatings. Since their introduction by the seminal paper of Alexander4, polymer brushes appeared a rational and direct tool to achieve surface control at the desired level. The structural versatility inherent in polymer chemistry, combined with the remarkable ease of integration of polymer brush technology into industrial production lines, has paved applied science avenues for this technology. A multitude of polymer brush architectures including homopolymers, gradient and block copolymers, polyelectrolytes, reversible and responding systems have been described5-7 featuring a variety of functions, with the actual frontier of adaptable and reproducible surfaces8. At the same time, many theoretical issues9-11 were addressed which led to important contributions to understanding the physics of polymer brushes.
