Facile synthesis of Ag nanowires enhanced PVB for transparent conductive film

Transparent conductive films (TCFs) are highly desirable for making full use of solar energy. However, the production and application of TCFs are seriously restricted by two obvious weaknesses: complex processes and poor properties. In this research, simple and direct approaches including condensation reflux and hot-pressing are selected to gain a cheap TCF with good properties. The polyvinyl butyral enhanced by 6 spray layers of Ag nanowires (AgNWs/PVB) TCF is found to achieve an optical transmittance of 80.1% and a sheet resistance of 86.4 Ω/sq, and meanwhile, withstand bending cycles over 150 and an extensile rate of 15%. Additionally, the AgNWs/PVB TCF has a deep potential to be further improved by hot-pressing treatment and its sheet resistance can be reduced to 19.7 Ω/sq. Our findings may show a facile way to produce low-cost and high-performance TCFs.
