▎ 摘　　要

By alternating deposition of poly (diallyldimethylammonium chloride) (PDDA) or silver nitrate, and graphene oxide (GO) sheets via electrostatic self-assembly process, two self-assembled multiplayer films (GO/PDDA film and GO/AgNO3 composite film) are successfully prepared. In order to make the films electrically active, a reduction treatment involving the thermal annealing in Ar/H-2 atmosphere at 600 degrees C are conducted. The films are studied by means of AFM, SEM, XPS, UV-Vis and four-probe resistance measurement instrument. The results show that these two kinds of films are surface uniform. And the graphene/Ag film has better optical properties and electrical properties. The transmittance of four layers graphene/Ag film is 85%, better than that of graphene film (72%); the sheet resistance of graphene/Ag film is 99.11 k Omega . square(-1), which is lower than that of graphene film (161.39 k Omega . square(-1)).
