碩士 === 國立清華大學 === 材料科學工程學系 === 104 === Modern optoelectronics, especially smart devices in unique fields like electronic skins, wearable electronics and robotic skins call for development of new flexible transparent electrodes (TEs).
In the present work, we synthesized ultra-long silver nanowires over 1 cm through a relatively fast, environmental friendly and facile galvanic displacement method without adding external capping agent. In addition,
inspired by biostructures, we developed a facile leaf venation (LV)-assisted dry transfer printing technique to fabricate the transparent electrodes with silver nanowires, assembling silver nanowires into LV-like network. The LV-like network of ultra-long silver nanowires can help achieve a remarkable balance between transparency and conductivity (ultra-high transparency of 95% with ultra-low sheet resistance of 5 Ω/sq simultaneously),which is attributed to the ever-evolution of LV structure to obtain an optimized balance between transparency and transportation of nutrition, as well as excellent mechanical flexibility. The process of fabricating TEs with bio-inspired concept is fast, low-cost and green, which is suitable for large scale production with remarkable electro-optical performances.
The last but not least, A chameleon-inspired e-skin was established via integrating a transparent flexible triboelectric nanogenerator (TENG) with a flexible electrochromic device (ECD) using our Ag NWs electrodes to
demonstrate the effectiveness of our TE, which shows a significant shorter response time (2.9s) compared to that with traditional ITO. It should be noted that the smart e-skin could be used to replace special effect in the performance of Sichuan Opera named face changing (changing of masks in quick succession to show different emotions and feelings of the character in the play) through relative interactions between dynamical friction induced by body motions and color of e-skin, as well as monitor the health conditions visually. It is of great significance that the smart e-skin with our TE opens up a possibility for every person to experience traditional facechanging culture in a simple and interesting way. In contrast, the art normally takes a very skillful person to perform.
In a word, we completed a creatively profound work through
highlighting versatile applications of nanotechnology to heath care and artistic activity with bio-inspired concept through a relatively simple way
