In this study, large-scale multifunctional transparent ITO nanorod films that exhibit extreme wetting states (superhydrophobicity or superhydrophilicity), high transmittance, low resistivity to infer antistatic properties, antifogging, and self-cleaning were fabricated on 2-in. glass wafers and various substrates (glass, Si, Sus of 2.5 x 2.5 cm) via radio frequency (RF)-magnetron sputtering deposition. An ITO nanorod film prepared for 60 min at 500 degrees C exhibited excellent optical (similar to 85% transmittance at 500 nm) and electrical (sheet resistance of similar to 90 Omega square(-1), antistatic property, with a figure of merit of 2.2 x 10(-3) Omega(-1)) properties. It also showed superhydrophilic property (with a water contact angle as low as 1 degrees) and antifogging. After coating with fluoroalkylsilane, the ITO nanorod film exhibited strong and stable superhydrophobic characteristics, having a high water contact angle (172.1 degrees), a near-zero sliding angle, and self-cleaning capabilities. It is expected that large-scale multifunctional transparent ITO nanorods will lead to further technological advancements in the area of novel optoelectrical applications and in future industrial applications.
