Abstract
Copper nanowires (CuNWs) have low cost and high conductivity and are prominent components to replace the cost rising indium tin oxide (ITO) transparent electrodes. However, the standard coating method of CuNWs resulting in transparent electrodes' adhesion, flexibility and thermal stability is inferior. In this paper, a highly transparent, conductive, and flexible tape is reported, the tape is obtained by transferring CuNWs to conventional transparent tape. We use the viscidity of the tape to protect the CuNWs from corrosion and mechanical damage and use the electroplating welding to reduce the junction resistance between CuNWs. The sheet resistance of the transparent conductive tapes obtained is ~20 Ω/sq with the transmittance of ~80%, at 550 nm wavelength. In addition, the thermochromic paint printed on the transparent conductive tape film is a remarkable heater application. • High-performance CuNWs based flexible transparent conductive tape are obtained. • The tapes show low sheet resistance ~20 Ω/sq with the transmittance of ~80%. • Anticorrosion and mechanical performances of CuNWs are enhanced significantly. • Flexible heater based on transparent conductive tape is prepared and demonstrated.
