A polydopamine coated goose down-Ag nanowires-poly(dimethylsiloxane) (PDA-GD-AgNWs-PDMS) flexible conductor with binary network structure was fabricated by a simple dip-coating method. The skeleton network of cross and twining GD combining with two-dimensional (2D) AgNWs network formed the binary conductive network, which allowed the PDA-GD-AgNWs-PDMS composite with high conductivity of 793.02 S/cm. And these conductors can retain high electrical conductivity under 125% strains due to the shape deformation of GD network and the enhanced adhesion between AgNWs and GD surface. Moreover, the conductor exhibit excellent electromechanical properties under bending or stretching (60%) in fatigue test. Due to the high conductivity, excellent electromechanical stability and facile fabrication method, the PDA-GD-AgNWs-PDMS composite might be potentially used as interconnects and electrodes for stretchable functional devices.
