Facile fabrication of highly conductive tracks using long silver nanowires and graphene composite

Flexible long silver nanowires and graphene (AgNW-G) hybrid tracks with ultra-low resistivity were prepared by a low-temperature sintering process. The long AgNWs connect the graphene flakes in a plane and establish bridges between graphene layers by building a 3D conductive network, and finally induce a resistivity of 8.6 mΩ cm with a concentration of AgNWs of 20 wt% and sintering at 150 °C. The AgNW-G tracks show superior reliability even after 100 bending cycles. The use of AgNW-G tracks in flexible circuits indicates their possible applications in flexible electronics.
