Controlled Synthesis of Cross-Linked Ultrathin Polymer Films by Using Surface-Initiated Atom Transfer Radical Polymerization

Ambient-temperature atom transfer radical polymerization of ethyleneglycol dimethacrylate from a surface yields homogeneous, cross-linked polymer films. The absence of polymerization in solution in this "living" procedure avoids physisorption and gives uniform, cross-linked films with controlled thicknesses from 3 to 300 nm.
