Curved copper nanowires-based robust flexible transparent electrodes via all-solution approach

InterNano Industry News - May 31, 2017 - 3:45am
Abstract Curved Cu nanowire (CCN)-based high-performance flexible transparent conductive electrodes (FTCEs) were fabricated via a fully solution-processed approach, involving synthesis, coating, patterning, welding, and transfer. Each step involved an innovative technique for completing the all-solution processes. The high-quality and well-dispersed CCNs were synthesized using a multi-polyol method through the synergistic effect of specific polyol reduction. To precisely control the optoelectrical properties of the FTCEs, the CCNs were uniformly coated on a polyimide (PI) substrate via a simple meniscus-dragging deposition method by tuning several coating parameters. We also employed a polyurethane (PU)-stamped patterning method to effectively produce 20 μm patterns on CCN thin films. The CCN thin films exhibited high electrical performance, which is attributed to the deeply percolated CCN network formed via a solvent-dipped welding method. Finally, the CCN thin films on the PI substrate were partially embedded and transferred to the PU matrix to reduce their surface roughness. Through consecutive processes involving the proposed methods, a highly percolated CCN thin film on the PU matrix exhibited high optoelectrical performance (R s = 53.48 Ω/□ at T = 85.71%), excellent mechanical properties (R/R 0 < 1.10 after the 10th repetition of tape peeling or 1,000 bending cycles), and a low root-mean-square surface roughness (R rms = 14.36 nm).

Transforming greenhouse gas CO2 into carbon nanotubes

InterNano Industry News - May 27, 2017 - 3:45am
In two new studies, researchers show that cement plants can have their carbon dioxide exhaust eliminated while co-producing carbon nanotubes. They demonstrate that with their C2CNT (carbon dioxide into carbon nanotubes) process, a wide portfolio of tailored carbon nanotubes, such as those with special shapes or conductivity can be made. C2CNT is a straightforward process that transforms CO2 to carbon nanotubes by molten electrolysis with inexpensive (nickel and steel) electrodes and low voltage. This synthesis consumes only CO2 and electricity, and is constrained only by the cost of electricity.
