Abstract
The fabrication of polymer brushes via surface‐initiated controlled radical polymerizations has progressively developed beyond a simple surface functionalization technique, enabling the design of complex polymer interfaces with a quasi‐3D molecular organization. The modulation of polymer brush structure has led to an extremely broad tuning potential for technologically relevant interfacial, physicochemical properties, allowing one to precisely tune swelling, nanomechanical, and nanotribological characteristics of polymer films. In addition, the synthesis of multilayer brush interfaces with hierarchical architecture has been exploited to control biological phenomena on modified platforms, such as cell adhesion and settlement, or to fully prevent biological contamination from bacteria. In this feature article, the most recent developments in the synthesis and application of quasi‐3D structured polymer brushes are summarized, placing particular attention on how the tuning of grafted‐polymer architecture could translate into a variation of interfacial characteristics.
