The grafting of polymer brushes to a solid surface provides a versatile tool for surface modification and functionalization. End-functionalized polymer chains may be grafted to the solid substrate (grafting to) or the grafting reaction can proceed by polymerization from the surface (grafting from). In both cases a thin polymer brush layer on the solid surface is formed, which determines the surface properties. The use of mixed brush layers is described, which provide switching and adaptive surface properties. A combination of surface roughness with mixed brushes can provide switchable ultra-hydrophobic surfaces.
