In this study, silver nanowires-graphene nanocomposites (AgNWs-GNs) have been successfully fabricated via a facile solvothermal synthetic method. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and UV-Visible absorption spectra (UV-Vis) were employed to characterize the structure and morphology of the as-prepared nanocomposites. The electrically conductive adhesive (ECA) was prepared by mixing AgNWs-GNs, micro-sized Ag flakes and epoxy together. The electrical and thermal properties of ECAs were tested after cured at 150 ?C for 2 h. The results show the AgNWs-GNs have a profound influence on the improvement of the electrical conductivity of the ECAs. When the content of the AgNWs-GNs was 0.9 wt%, the ECAs have the lowest volume resistivity of 4.34 ? 10-4 Ω?cm. Moreover, the ECAs filled with AgNWs-GNs still possessed the great thermal stability.
