Highly stretchable and transparent electrode film based on SWCNT/Silver nanowire hybrid nanocomposite

Recent Progress in Transparent Conductors Based on Nanomaterials: Advancements and Challenges

“…It is also clear that numerous materials have been able to come close to the standards set by ITO (transparency >90% and Sheet resistance of ≈10 Ω sq −1 ) with some even exceeding. The hybrid material of SWCNT/AgNW TSCs came close to meeting the transparency and conductivity with low stability (20% in tensile strain) 75. AgNW/RGO/PU hybrid TSCs showed great potential to replace ITO as its characteristics exceed ITOs with a moderate stretchability (50% in tensile strain) however, multiple post‐processing treatments like oxygen plasma treatment and thermal annealing would increase production cost 71.…”

“…The slit between the metal wires winding the rod allows the nanomaterial solution to be coated thinly and uniformly. Hwang et al fabricated a large SWCNT/AgNW hybrid layer on thermoplastic polyurethane substrate 75. This method could be applied to a large processing area,21 or to align nanomaterials with the dragging direction of the rod with appropriate dragging speed, concentration of solution, and slit size 79…”

“…Applications include temperature maintenance in industrial processes, heating of microchannel chips, and defogging surfaces in cold climates. Medical thermotherapy can benefit from stretchable and transparent electrodes 43,75. Important qualities in electric heaters are uniform and steady heating, fast heating and cooling response times, and stability during stretching 43.…”

“…The fabricated electrode also demonstrated improved anti‐electromigration properties, sheet resistance of 62.3 Ω and transmittance of 83.4%. TSCs designed for film heaters were also fabricated by Hwang et al with AgNW and SWCNT in a sandwich structure using a simple wet coating technique that exhibited superb optical properties 75. Joule heating in the conductor could produce a temperature of more than 50 °C in 50 s. The conductor also demonstrated excellent environmental endurance with no decrease in performance in high temperatures (85 °C) and humidity (85%).…”

“…For example, solar cells require a high haze to maximize their energy conversion efficiency and increase the absorption of light that enters the cell. Low haze values of less than 0.5% in 60 Ω sq −1 sheet resistance are required for applications in visual displays 75. Controlling the haze of the transparent conductor is an issue that warrants further investigation to improve optoelectrical devices.…”
