AI Article Synopsis
- The report details a method for depositing nickel (Ni) onto specific micropatterns created with poly (acrylic acid) (PAA) on self-assembled monolayers (SAMs).
- PAA is applied to the surface, where UV light exposure binds it only to the regions not covered by a photomask, allowing the rest to be washed away.
- A palladium (Pd) catalyst is then attached to the PAA areas, which prompts nickel plating when the substrate is dipped in a nickel sulfate solution.
Article 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(SO ) bath.
