Abstract
| - Carbon nanotubes (CNTs)-mediated self-assembly of metal (Au and Ag) nanoparticles at the liquid/liquid interfacein the form of a stable nanocomposite film is reported. The metallic luster results from the electronic coupling ofnanoparticles, suggesting the formation of closely packed nanoparticle thin films. The interfacial film could be transferredto mica substrates and carbon-coated transmission electron microscopy (TEM) grids. The transferred films were verystable for a prolonged time. The samples were characterized by UV−vis spectroscopy, scanning electron microscopy(SEM), TEM, and X-ray photoelectron spectroscopy (XPS). SEM and TEM results show that the films formed at theliquid/liquid interface are indeed composite materials consisting of CNTs and nanoparticles. XPS measurementsfurther indicate the presence of the interaction between nanoparticles and CNTs.
