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 ofthe silver nanowires are found.The possible formation mechanism for the silver nanowires is briefly discussed.
