Copper nanowires (CuNWs) endowed with oxidation stability without impairing their conductivity is highly desirable for their practical applications. This work demonstrates a green and cost-effective method to produce a stable copper nanowires-graphene nanosheets composite (CuNWs-GNs), and the electrodes based on CuNW-sGNs were fabricated. The CuNWs with a high-aspect-ratio of 1778 in-situ grown directly between the high crystalline GNs interlayers, thereby obtained a multilayer protective shield of GNs. The electrodes fabricated by a filtration method possessed high electrical conductivity of 2.77 x 10(6) S.m(-1). The relative resistance ratio of the electrodes increased only 1.27 and 1.92, respectively, after aging at 25 degrees C and 60 degrees C for 46 days, which suggested that the electrodes had excellent oxidation stability. The transparent flexible electrodes (TFEs) fabricated on a polyethylene terephthalate sheet by a spray coating method presented an excellent transmittance of about 89% at an electrical resistance of 81.42 Omega/sq. The TFEs demonstrated impressive mechanical flexibility against 1000 bending cycles and in different radius curvature ranging from 1 mm to 30 mm. This approach sheds light on solving the big issue of the instability of CuNWs and promote their applications in a modern electronic device.
