We demonstrated for the first time a facile and reproducible preparation of large-scale (similar to 40 m(2)) initiator layers for surface-initiated atom transfer radical polymerization (SI-ATRP) using a simple sol-gel solution of (p-chloromethyl)phenyltrimethoxysilane and tetraethoxysilane. Highly smooth and transparent initiator layers could be formed on various inorganic/organic substrates via a spin-, wire-bar-, or roll-to-roll-coating without any marked change in surface morphology or bulk properties at room temperature. Combining the advantages of this sol gel approach and subsequent paint on SI-ATRP using a variety of waterborne monomers, we have succeeded in the formation of polymer brushes on large-scale real-life substrates (i.e., maximum 50 x 50 cm(2)) under ambient conditions (room temperature and open to the air) without any complicated apparatus or harsh reaction conditions.
