Designed surface construction by photo-induced vapor-phase assisted surface polymerization of vinyl monomers using immobilized free radical initiators.

ABSTRACT

To build up finely designed patterns on solid surfaces, consecutive vapor-phase assisted surface photo-polymerization (VASP) of methyl methacrylate and styrene was carried out under UV-irradiation through a stripe-patterned photo-mask on Si-wafer and Au-plate surfaces, resulting in the reproduction of designed and multi-layered patterns made of block copolymer chains grafted from the surfaces.
