WebAbstract. 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 ...
