Abstract:
1. A method of producing transition metal surfaces modified by (co)polymers synthesized using Reversible Addition-Fragmentation chain Transfer (RAFT), comprising: forming a thiocarbonylthio end-capped (co)polymer by reacting a polymerizable monomer or co-monomers with a free radical source and a thiocarbonylthio chain transfer agent (CTA) using the RAFT method in a solvent solution; contacting the transition metal surface with the end-capped (co)polymer; and introducing a reducing agent into the solution of end-capped (co)polymer and transition metal surface to simultaneously reduce the thiocarbonylthio end-capped (co)polymer and the transition metal surface so as to anchor the (co)polymer directly to the transition metal surface.
