<Abstract>

We propose a versatile yet practical transferring technique to fabricate a high

performance and extremely stable silver nanowire (AgNW) transparent electrode

on arbitrary substrates. Hydroxylated poly(ethylene glycol) terephthalate (PET)

or poly(dimethylsiloxane) (PDMS) deposited with AgNWs was selectively decorated

to lower its polar surface energy, so that the AgNWs were easily and efficiently

transferred into an epoxy resin (EPR) as a freestanding film (AgNWs–EPR) or onto

various substrates. The AgNWs–EPR capped with alkanethiolate monolayers

exhibits high conductivity, low roughness, ultraflexibility, and strong corrosion

resistance. Using the transferring process, AgNWs–EPR was successfully constructed

on rough, adhesive, flimsy, or complex curved substrates, including PET, thin optically

clear adhesive, papers, a beaker, convex spherical PDMS, and leaves. A flexible touch

panel enabling multitouch and a curved transparent heater on a beaker were first

fabricated by using the composite film. These demonstrations suggest that the proposed

technique for AgNWs is a promising strategy toward the next generation of flexible

/portable/wearable electronics.
