Site-Specific Polymerization of Methacrylate Monomers

The patterned organosilane monolayers introducing organolsilane molecule with a polymerization initiating unit are useful as template surfaces for site-specific polymerization. Atom transfer radical polymerization (ATRP) unit was immobilized as a monolayer component. Since ATRP is one of the most successful methods for polymerizing a variety of monomers in a controlled fashion [44, 45], tailor-made surface topography is possible. Several reports have described the formation of polymer thin film by the radical polymerization from the immobilized ATRP initiator [46, 47],

The width estimated from the AFM image is in good agreement with the line width of surface initiator micropatterns. The formation of a PMMA layer was further confirmed by XPS measurement, in which the characteristic peaks attributed to aliphatic carbon, the ether carbon, and carbonyl carbon were observed at 285, 286.5, and 288.8 eV, respectively.
