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. Copyright © 2016 John Wiley & Sons, Ltd.
