Abstract

We report on the preparation and characterization study of new nanoporous reduced grapheme oxide (rGO) film fabricated from electrostatic layer-by-layer assembly of gold nanoparticles (gold- NPs) and rGO. Well distributed gold-NPs in multilayer film means that the gold-NPs can be readily dissolved by the addition of cyanide ions, which allows for a direct and precise comparison of the porosity of multilayer thin films based on rGO under the presence and absence of the gold-NPs. In addition, the LbL assembly methods offers the big advantages of possibilities in mass production and 2-dimensional nano-objects based film prepared from large size substrates. We expect that this demonstration offers a new route to introduce nanopore into multilayer thin films and opens up the possibility of building more complex functional multicomponent nanoporous structure consisting of 2-dimensional nano-objects, which are believed to be useful for nanodevice systems.
