One-Pot Synthesis of Superfine Core–Shell Cu@metal Nanowires for Highly Tenacious Transparent LED Dimmer
We demonstrate a
one-pot, low-cost, and scalable method for fast synthesis of superfine
and uniform core–shell Cu nanowires (NWs) coated with optional
metals and/or alloy. Cu NWs in high aspect ratio (>3000) were synthesized
through an oleylamine-mediated solution method, and tunable shell
coating was performed by injecting metal-organic precursors at the
last stage of reaction. Superfine Cu@metal NWs (Ti, Zn, V, Ni, Ag,
NiZn, etc) were achieved in diameter of ∼30 nm and length of
∼50 μm. Transparent conductive films were obtained by
imprinting method, showing high optoelectronic performance (51 Ω/sq
at 93% transmittance), high mechanical tenacity over bending, twisting,
stretching, and compressing, and robust antioxidant ability (high
temperature and high humidity). A transparent film dimmer for light-emitting
diode (LED) lighting was fabricated with the stretchable Cu@Ti NWs
network. The LED luminance could be accurately tuned by the deformation
strain of Cu@Ti NWs film
