Abstract
This study has been separated into four chapters. Chapter 1 is the general introductions of transparent flexible electrodes. Chapter 2 includes the synthesis and improvement of silver nanowires (AgNWs), colorless polyimides and the preparation of highly flexible transparent electrodes. Chapter 3 depicts the applications such as electrochromic and snow-cleaning devices based on AgNWs-PI transparent electrode. The last chapter is the conclusions. In this study, both transparent and flexible electrode with highly thermal stability was successively prepared by the coating technique of silver nanowires (AgNWs) and polyimides (PI). In order to enhance the optical and electrical properties of hybrid film, the synthetic of higher aspect ratio AgNWs also have been discussed in particular. Because of the introduction of high performance polyimides as substrate and protector, the AgNWs conductive networks not only exhibited good adhesive property and bendability, but showed excellent thermal stability. Owing to the high glass transition temperature (Tg) of polyimides, the resulted AgNWs-PI electrode could maintain conducting property at high temperature environment. Thus, the hybrid electrode provided extremely high potential to operate at harsh working environment or further post processing. In addition, the optimized processing parameters were then used for applications of electrochromic and snow-cleaning devices which have been discussed in chapter 3. The devices fabricated by silver nanowires and colorless polyimide hybrids also showed excellent long-term stability.
