| Abstract
| - Selective electroless nickel plating was demonstrated at the micron scale on 3-D surfacemicrostructures using a two-step method. The 3-D patterned and functional surfacemicrostructures consisted of microparticles, polyelectrolyte multilayers, and self-assembledmonolayers, which were built by microcontact printing and directed self-assemblies ofpolyelectrolytes and particles. Selectively nickel-plated surfaces were characterized withoptical microscopy, X-ray photoelectron spectroscopy, scanning electron microscopy, andenergy-dispersive X-ray spectroscopy. Charged Pd catalyst complexes were first depositedon oppositely charged functional surfaces, and then were reduced to elemental nickel (0)selectively where the Pd complex was deposited on the surface. In this work, it wasdemonstrated that selective electroless nickel plating on complex 3-D microstructures withsubmicron resolution could be achieved using a two-step electroless plating method.
- Selective electroless nickel plating was demonstrated at the micron scale using a two-step method. Functional and patterned model surfaces consisting of carboxylated polystyrene particles, polyelectrolyte multilayers, and EG SAM regions have been systematically tested using two Pd-based catalysts.
