Abstract
Silver nanowires-silver nanoparticles-graphene nanosheets (AgNWs-AgNPs-GN) hybrid nanomaterials were fabricated through a hydrothermal method by using glucose as a green reducing agent. The charge carriers of AgNWs-AgNPs-GN passed through defect regions in the GNs rapidly with the aid of the AgNW and AgNP building blocks, leading to high electrical conductivity of electrically conductive adhesives (ECA) filled with AgNWs-AgNPs-GN. The morphologies of synthesized AgNWs-AgNPs-GN hybrid nanomaterials were characterized by field emission scanning electron microscope (FESEM), and high resolution transmission electron microscopy (HRTEM). X-ray diffraction (XRD) and laser confocal micro-Raman spectroscopy were used to investigate the structure of AgNWs-AgNPs-GN. The resistance of cured ECAs was investigated by the four-probe method. The results indicated AgNWs-AgNPs-GN hybrid nanomaterials exhibited excellent electrical properties for decreasing the resistivity of electrically conductive adhesives (ECA). The resistivity of ECA was 3.01 × 10−4 Ω·cm when the content of the AgNWs-AgNPs-GN hybrid nanomaterial was 0.8 wt %.

Summary
Metal nanomaterials have attracted a great deal of research attention and have tremendous potential in a variety of high-performance antibacterial applications [1], catalysts [2,3,4,5], sensors [6,7,8], optoelectronic devices and electronics [9,10,11]. Many kinds of 1D nanomaterials have been investigated to produce conductive composites, especially AgNWs, and they have drawn prodigious interest for several reasons, such as their stable chemical properties and high electrical conductivity [21,22]. AgNWs may improve the conductivity of ECAs in yet another way They are excellent materials to supply junctions for wire-built networks, and so the number of conductive pathways can be increased and the effective contact area can be enlarged. AgNWs-AgNPs-graphene nanosheets hybrid nanomaterial is used as conductive filler in ECA instead of partial silver flakes. This work demonstrates that a system containing AgNWs and AgNPs is an efficient way to provide the electronic transmission channels of Ag-Ag junctions on the surface of graphene [30], while simultaneously decreasing the resistivity of the ECA containing AgNWs-AgNPs-GN hybrid nanomaterials
