Oxygen (O2)-mediated controlled radical polymerization was performed on surface under ambient conditions, enabling on-surface polymer brush growth under open-to-air conditions at room temperature and free of metal contamination. Polymerization of zwitterionic monomers using this (O2)-mediated surface-initiated RAFT (O2-SI-RAFT) polymerization method provided a hydrophilic surface, which exhibited antibiofouling effects. This O2-SI-RAFT polymerization strategy can avoid prior deoxygenation steps or the use of inert conditions for polymerization, thus it could be applied for the substrates with large surfaces under ambient benchtop conditions, enabling surface functionalization in a practical and user-friendly manner. |
