本論文利用單壁奈米碳管本身為高長徑比且具有優異導電能力的特性,當作可撓式透明導電膜上的導電材料:同時製備單壁奈米碳管奈米銀顆粒的奈米複材以及合成奈米銀線,配製成導電漿料後製備成可撓式的透明導電薄膜。
首先,利用表面電漿改質技術,將單壁奈米碳管表面有機化以克服奈米碳管本身凡德瓦力造成的嚴重糾結,將改質後的單壁奈米碳管以塗佈棒法及轉印法製備透明導電薄膜,並以轉印法直接製備出不同大小的奈米碳管導電圖案,而不需要任何額外的蝕刻步驟;並將以電漿改質的奈米碳管當作基板,將奈米銀顆粒成長於其上,重覆同樣的步驟製備透明導電薄膜,並以高溫熱壓得到片電阻值更低的薄膜,由實驗結果得知,在透光度約82%的情況下,片電阻值從450Ω/sq下降到350Ω/sq;額外合成直徑約150~200nm的奈米銀線,與奈米碳管奈米銀顆粒複材混摻成導電漿料,製備成薄膜後以高溫熱壓,得到片電阻值300Ω/sq,透光度81.0%的可撓式透明導電薄膜,為本論文最佳數據。
This study use singled-wall carbon nanotubes as the major material in fabricating flexible transparent conductive films in the reason that SWNT is high in aspect ratio and shows a good ability in conducting. At the same time, we use the plasma-treated SWNT as substrate growing silver nanoparticles, turning into nanocomposites. First, we prepared the SWNT that have treated by the plasma then grafted the maleic anhydride (MA) on the surface of the SWNT to improve the severe entanglement cause by SWNT’s van der Waals force. We use two different process fabrication flexible transparent conductive film, rod printing and transfer printing, and we directly make different conductive patterns by transfer printing without any etching process. Furthermore, we use the as-prepared SWNT as substrates growing silver nanoparticles turning into nanocomposites, and use thess nanocomposites as materials repeating the same process as transfer printing of transparent conductive films, after hot pressing, surface resistance lower to 350ohm/sq in 82% transmittance, meanwhile, the pure SWNT transparent conductive film is 450ohm/sq in 82% transmittance. Additionally, we synthesize silver nanowires mixing with SWNT-MA-Ag nanocomposites as conductive slurry and fabricate transparent conductive film, after hot pressing, surface resistance lower to 300ohm/sq in 81% transmittance, which is the best data of this research.
