Manufacturing and Application of Nano-silver wires and rods

指導教授 : 林清彬

摘要


本研究以氯化銀/銀原子簇晶種合成法製備奈米銀線棒,將所製作的奈米銀棒製成奈米銀棒乙醇溶液之導電墨水。將感光性樹脂混合奈米銀棒浸塗於蜘蛛絲,會在蜘蛛絲親油端處形成紡錘體透鏡,藉由RGB雷射照射藉以觀察紡錘體透鏡之光子奈米噴流特徵,以期克服光學顯微鏡無法避免的繞射極限問題。藉由氯化銀薄膜複合加奈米銀棒提出一種嶄新的Orange II偶氮染料降解方法。我們將製備的奈米銀晶種在160℃環境下加入聚乙烯吡咯烷酮(PVP)及硝酸銀合成高展弦比的奈米銀線溶液,在室溫下利用往復式活塞唧筒衝擊奈米銀線溶液後得到低展弦比奈米銀棒,破壞與重新成長過程中節錄一系列TEM圖藉以說明奈米旗幟與奈米銀棒的成長機制,並與滲透理論相互印證。感光樹脂混合奈米銀棒的紡錘體在紅光(波長617nm)於3μm穿透厚度下產生的光子奈米噴流特徵接近繞射極限。氯化銀複合奈米銀棒薄膜在紫外和可見光照射下對Orange II偶氮染料的光催化降解具有完全脫色效果。

In this study, nano silver rods were prepared by silver chloride/silver cluster seed crystal synthesis method and UV exposure and the prepared silver nanorods glycol solution was applied to the conductive ink and photo curable resin coating. The photocurable resin mixed nano silver rod is dip coated on the spider silk, and a spindle lens is formed at the oleophilic end of the spider silk, and the photonic nano jet characteristics of the spindle lens are observed by RGB laser irradiation, in order to overcome the problem of diffraction limit that the optical microscope is hard to avoid. This study proposes a process for fabricating nano-silver crystal seeds and silver nanowires / nanorods that were prepared by seed synthesis method The formed spider silk spindle is used to observe and study the photonic nanojet characteristics in order to overcome the problem of diffraction limit that the optical microscope is hard to avoid. It also proposes a renewal Orange II degradation method by a film of silver chloride and silver nanorods glycol solution. In this process, UV-irradiated silver chloride nanoparticles are added to ethylene glycol solution containing polyvinyl pyrrolidone (PVP) and silver nitrate at 160 C. With the seed crystal synthesis method, this process yielded a solution containing silver nanowires with high aspect ratio (AR) in the ambient, and using a reciprocating piston cylinder to impact the silver nanowires solution at room temperature to obtain a low aspect ratio silver nanorods, In the process of destruction and re-growth, a series of TEM images are recorded to illustrate the growth mechanism of the nano-flag and the nano-silver rod, and demonstrate the theory of percolation. The photonic nanojet characteristics of the spider silk spindle coating with photosensitive resin and nanorods mixed solution at red light (wavelength 617 nm) on a penetration thickness of 3 μm approach the diffraction limit. The silver chloride and nano-bar silver film has complete decolorization effect on the photocatalytic degradation of Orange II azo dye under ultraviolet and visible light irradiation.
