| 摘 要： | 为改善产品长径比,本文在经典多元醇法的基础上,经过常压滴注路线和密闭溶剂热路线分别制备银纳米线。详细讨论了反应时间、反应气氛及反应物投料比等相关参数对银纳米线的产率和长径比的影响。发现密闭溶剂热法在缓解环境污染的同时降低了生长过程中的扰动,所得银纳米线平均直径约55 nm,长度约65μm,长径比接近1 200。以之制备的透明导电薄膜的方阻仅6Ω,波长550 nm下透光度为78. 6%,品质因数(FOM)高达246,优于常压滴注路线。

| Abstract: | Silver nanowires(AgNWs)were prepared by atmospheric drip route and hermetic-solvothermal route respectively to enhance the aspect ratio of classic polyol method products. The effects of reaction time,reaction atmosphere and reactant feed ratio on the yield and aspect ratios of Ag NWs were discussed in detail. The Ag NWs growth process was more eco-friendly and less disturbances in hermetic-solvothermal route. The AgNWs products show that an average diameter of approach 55 nm and length of about 65 μm and a high aspect ratio of about 1 200. The transparent conductive film fabricated by hermetic-solvothermal AgNWs exhibit sheet resistance of 6 Ω at 78. 6% transmission of 550 nm and a factor of merit(FOM)of 246,better than that of atmospheric drip route. |
