▎ 摘　　要

This study present a general approach for the preparation of Ag-Grapheme nanocomposites in a water-ethylene glycol system using graphene oxide as a precursor and Ag as building blocks. The metal nanoparticles are adsorbed on graphene oxide sheets and play a pivotal role in catalytic reduction of graphene oxide with ethylene glycol, leading to the formation of Ag-Grapheme nanocomposites. The morphology and structure of the obtained material are examined by XRD, SEM, TEM and FT-IR. The size and morphology of the particles are influenced by the the concentration of AgNO3 solution. Because of the existence of Ag particles, graphene sheets are well separated in the film obtained via vacuum filtration method. The electroconductibility of graphene/Ag film is investigated by four point resistivity test system. It is found that the electroconductibility of the film is increasing with the rising of the AgNO3 solution concentration and the maximum value is 2.94scm(-1) with the 0.15mol L-1 AgNO3 solution.
