Bio-inspired semi-transparent silver nanowire conductor based on a vein network with excellent electromechanical and photothermal properties.

ABSTRACT: A bio-inspired conductive binary-network of vein-silver nanowires (AgNWs) was embedded in poly(dimethylsiloxane) (PDMS) to prepare a semi-transparent stretchable conductor (vein-AgNWs-PDMS) by a simple dipping process. The special conductive structure was constructed by using veins with a porous structure as an ideal skeleton to load AgNW networks, which allowed the vein-AgNWs-PDMS composite to show a low sheet resistance of 1 Ω sq^-1 with 74% transmittance. The figure of merit of vein-AgNWs-PDMS is as high as 2502 and can be adjusted easily by controlling the times of the dipping cycle. Furthermore, the vein-AgNWs-PDMS conductor can retain high conductivity after 150% mechanical elongation and exhibit excellent electromechanical stability in repeated stretch/release tests with 6
