▎ 摘　　要

With the fast development of inkjet printing, the fabrication and application of conductive ink have been the frontiers of scientific research. Compared with traditional conductive inks, the rise of graphene also reveals greatly potential applications and attracts many attentions all around the world. In this work, graphene conductive inks with and without Ag nanoparticles were prepared by direct physical methods. Through TEM characterizations, it can be clearly found the resistance of graphene without additional Ag nanoparticles is larger than that of graphene decorated by Ag. Meanwhile, the annealing process also plays an important role in increasing the conductivity of graphene-Ag system. The conductivity obtained in this work follows a rule of sigma(annealed)>sigma(with) (precursor)>sigma(w/o) (precursor)>sigma(pure) (G). Our work not only offers a reference for exploring high conductive graphene composites but also opens a way for investigating the real mechanism at the interface in graphene composites system.
