Abstract

Polymer brushes are monolayers of one-end tethered polymer chains at high graft density on a surface. Owing to the steric interactions between the tethered polymer chains within the brush regime, this class of polymer thin films has unique properties compared to the conventional polymer thin films. Polymer brushes provide an elegant route for surface modification owing to their excellent mechanical stability as well as functional versatility. Among the polymer brush synthesis methods, surface-initiated polymerization (SIP) offers a unique opportunity for the generation of high graft density polymer brushes. Combined with controlled/living polymerization, the SIP method revolutionized the polymer brush synthesis and allowed the tailoring of surface properties of these molecular thin films. The control of surface properties provided new ways to change wettability, lubrication, and the interaction of biological macromolecules/cells to surfaces and created new opportunities in the design of responsive surfaces, smart materials, biocompatible surfaces, and various biotechnology and nanotechnology applications. This field is rapidly emerging with wide range of applications in multiple research fields and is promoting cross-disciplinary research.
