Abstract
Silver nanowires (AgNWs) >100 μm and even 160 μm in length have been synthesized using a facile and rationally designed solvothermal method by heating preservation at 150 °C. The length of the as-synthesized AgNWs is over 4–5 times longer than those previously reported, while the diameter range is from 40 nm to 85 nm. A transparent conducting film (TCF) was fabricated using hydroxyethyl cellulose (HEC) as the adhesive polymer, and it achieved exceptional and stable optoelectronic properties. Its low sheet resistance of ∼19 Ω sq−1 (on polyethylene terephthalate, PET) and high optical transmittance of ∼88% are superior to that of expensive indium tin oxide (ITO) films. More significantly, the AgNW network demonstrates excellent adhesion to PET substrates. This study indicates that ultra-long silver nanowires can serve as an alternative to ITO, which also demonstrates its potential application in flexible electronic devices.
Highlights
Along with the rapid development of exible electronic devices, such as exible solar cells, exible displays, organic light emitting diodes (OLEDs), and so on, the supply of and demand for exible transparent conductive lms (TCFs) is increasing

It is observed that the preparation technology has revealed many shortcomings, such as tough experimental conditions, complicated synthesis processes, and the growth of nanowires is very sensitive to the presence of impurities, and so on
Summary
Along with the rapid development of exible electronic devices, such as exible solar cells, exible displays, organic light emitting diodes (OLEDs), and so on, the supply of and demand for exible transparent conductive lms (TCFs) is increasing. The length range of the reported AgNWs is from 0.5 mm to 31.2 mm, which are summarized in Table 1.6,9–23 Some reports have proved that the performance of the AgNWs relies mainly on the nanowire structure, such as diameter, length, dispersity, and so on.[24,25] More importantly, the lengths of AgNWs are key elements for forming the high transmittance with a low haze, and low sheet conductivity. This is due to longer AgNWs can form a more
