高长径比银纳米线是全印制电子技术中的关键材料之一。采用紫外-可见分光光度法研究了银纳米线制备过程中的变化，用 XRD、SEM 研究了产物晶体结构及形貌，讨论了模板剂的用量及溶液 pH 值对纳米银形貌的影响。结果表明，以十六烷基三甲基溴化铵为模板剂，采用一步水热法可制备出长度为50μm、直径为40 nm的银纳米线。在模板剂浓度为5.8×10–3 mol/L、溶液pH 值=11的实验条件下，可获得高长径比为1300的银纳米线。

Silver nanowires (Ag NWs) with high aspect ratio were one of the key materials of full printed electronic technology. Transition of reaction solution taken at different reaction time was measured by UV-visible adsorption spectra. Obtained products were characterized with XRD and SEM. Ag NWs (with an average diameter of 40 nm and length at least 50 μm) were synthesized by one-pot hydrothermal method in the presence of cetyltrimethylammonium bromide (CTAB) which acted as structure template. The morphologies of Ag nanostructures were changed by adjusting concentration of CTAB and pH value of reaction solution. High aspect ratio (≈1 300) Ag NWs are obtained when the concentration of CTAB is fixed at 5.8×10–3 mol/L and the pH of solution is 11.
