摘　　要：以聚乙烯吡咯烷酮（PVP）为表面活性剂、乙二醇为溶剂，通过简易的溶剂热方法合成了银纳米线。结果表明，在反应体系中乙二醇不仅能作为溶剂，而且还能起到还原剂的作用。用XRD、SEM对产物进行了表征。考察了乙二醇和PVP用量等对银纳米线合成的影响；找出了合成的较佳条件。对银纳米线的合成机理进行了初步探讨。Silver nanowires are prepared by a simple solvothermal reaction with ethylene glycol as solvent and poly N-vinylpyrrolidone（PVP） as surfactant. Results show that ethylene glycol not only serves as solvent but also reducing agent during the reaction. The products are characterized by XRD,SEM. The effects of the dosage of ethylene glycol and PVP on the preparation of silver nanowires are investigated in details. Results demonstrate that the dosage of ethylene glycol and PVP exert significant influence on the synthesis of silver nanowires. The optimal reaction conditions for the preparation of the silver nanowires are found. The possible formation mechanism for the silver nanowires is briefly discussed.
