博士 === 淡江大學 === 機械與機電工程學系博士班 === 106 === 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.
