摘要：

Aggregation and restacking of graphene nanosheets (GNS) can be efficiently inhibited by decorating the silver nanoparticles on the surface of GNS to form GNS/silver (GNS-Ag) composites, which can construct high transparent and electrically conductive thin films. Silver nanoparticles act as a useful nanospacer and conductor, which not only increase the interlayer distance but also improve the electrical conductivity between layers. A two-step reduction process using sodium borohydride and ethylene glycol was also demonstrated reducing graphene oxide to GNS efficiently. The GNS-Ag composite films showed a maximum sheet resistance of 93 Omega square(-1), while maintaining up to 78% light transmittance, which was two order of magnitude lower than that of GNS (8.2 x 10(3) Omega square(-1), 81%), and the value of DC conductivity to optical conductivity ratio was 13.5 instead of 0.25.
