Abstract

Abstract : This report demonstrates the electroless deposition of Ni onto micropatterns of poly (acrylic acid) (PAA) photografted to phthalimide‐terminated self‐assembled monolayers (SAMs). PAA is spin‐coated onto phthalimide SAMs and covered with a photomask. UV irradiation selectively binds PAA to exposed regions of the surface, allowing PAA on unexposed regions to be rinsed off. A Pd catalyst is then selectively adsorbed to regions of the surface where PAA is bound. The adsorbed catalyst selectively initiates Ni plating upon immersion of the substrate into a Ni(SO4 ) bath. Abstract : Macromolecular films are photochemically grafted to the surface of a phthalimide‐terminated self‐assembled monolayer, providing a robust scaffold for adsorbing catalysts that can initiate the electroless deposition of metals. In conjunction with a photomask, electroless deposition can be patterned. Ni is electrolessly deposited on photogenerated patterns of surface‐grafted poly (acrylic acid).
