Adsorption and adhesion studies of PdSn-nanoparticles on protonated amine and carboxylic acid-terminated surfaces

摘要

Electroless plating of acrylonitrile-butadiene-styrene-terpolymers (ABS-plastics) is used for decorative applications and relies on the immobilization of catalytic palladium-tin nanoparticles. We used chemical force microscopy to measure the adhesion force of palladium-tin nanoparticles on a patterned amine and carboxyl-terminated surface prepared by micro-contact printing. The kinetics of the adsorption process and the population density of the nanoparticles on amine and carboxyl-terminated surfaces were monitored by quartz crystal microbalance with dissipation analysis. The surface chemistry was investigated by means of polarization-modulated infrared reflection absorption spectroscopy and X-ray photoelectron spectroscopy. Enhanced adhesion and population density of PdSn nanoparticles on protonated amine-terminated surfaces compared with carboxyl-terminated surfaces is observed.
