The in situ CuS nanoparticle/polyelectrolyte multilayer (NPs/PEM) films have been prepared using the layer-by-layer method and the in situ synthesize method. The NPs/PEM films were characterized by atomic force microscope (AFM), ultraviolet-visible (UV-vis) spectroscopy, X-ray photoelectron spectroscopy (XPS), and transmission electron microscope (TEM). It was found that the adhesive forces between probe and sample are decreased by compositing in situ CuS nanoparticles. From the investigation of the nano- and micro-tribological behaviors, the NPs/PEM film has a lower friction force and a better anti-wear property than the pure polyelectrolyte multilayer film.
