Synthesis of Silver Nanowires and its Application on Stretchable Conductor

Abstract

In this paper, the silver nanowires (AgNWs) were synthesized by polyol process. Then the stretchable conductor was fabricated with a simple, low cost and low energy consuming method. The testing results showed that the synthesized AgNWs were 80 nm in diameter and 3~50 μm in length. Meanwhile, the thickness of AgNWs film was discussed as an effect factor to the resistance stability of stretchable conductor. Finally, through optimizing the thickness of AgNWs film, the stretchable conductor kept relatively stable resistance when the conductor was stretched to 50 times in length. The strain sensor was prepared using stretchable conductor as electrodes showed excellent linearity under a very large strain range and the minimum detectable strain is 0.89%.
