摘要:

采用改进的乙二醇法,通过调控Cl-物质的量、聚乙烯吡咯烷酮(PVP)物质的量和反应温度,高效合成了直径约130 nm、长度约150 μm、长径比约1 150的银纳米线(AgNWs)。所有原料在反应前一次性投入,无需使用注射泵等设备严格控制组分含量,合成的AgNWs纯度高,杂质少;同时,以过滤的方式提纯,洗涤两次即可得到极为纯净的银纳米线,适合规模化生产。通过旋涂的方式在石英玻璃基底上构建AgNWs导电网络,结果表明,550 nm处的透光率高达95.5%,薄层电阻低至52.0 Ω/sq,具有优异的光电性能。

关键词: 高长径比, 大直径, 过滤, 高透射率, 低薄层电阻

Abstract:

An improved ethylene glycol method was used to efficiently synthesize silver nanowires with a diameter of about 130 nm, a length of about 150 μm, and L/D was about 1 150 by adjusting the content of chloride ions, the amount of polyvinylpyrrolidone (PVP) and the reaction temperature. All raw materials are put in one time before the reaction, no need to use syringe pumps and other equipment to strictly control the content of components. The synthesized silver nanowires have high purity and few impurities. At the same time, it was purified by filtration and washed twice to obtain extremely pure silver nanowires, which is suitable for large?scale production. The conductive network of silver nanowires was constructed on the quartz glass substrate by spin coating. The results show that the light transmittance at 550 nm is 95.5%, the sheet resistance is 52.0 Ω/sq, and it have excellent photoelectric properties.

Key words: High aspect ratio, Large diameter, Filtration, High transmittance, Low sheet resistance
