Surface-initiated reversible addition-fragment chain transfer polymerization with oxygen (O2-SI-RAFT) was performed on a variety of substrates (silicon, titanium, glass, stainless steel, and nylon) in the presence of air. O2-SI-RAFT polymerization was possible with many different monomers including methacrylate, methacrylamide, and methacrylic acid. In addition, it was allowed to polymerize block copolymer brushes. Field emission scanning electron microscopy (FE-SEM) confirmed that poly(2-hydroxyethyl methacrylate) (PHEMA) brushes grew up to 850 nm on Ti/TiO2 substrates.
