摘要：
Polyvinylpyrrolidone (PVP) has been used to control size and shape of metal nanoparticles in aqueous solution, where PVP plays the dual role of protective and reducing agent. The influence of PVP with different molecular weight on the aspect ratio of nanorods and nanowires during a classical polyol process was studied. Nanowires with higher aspect ratio were obtained by using PVP with higher molecular weight. It is suggested that the reduction rate is decreased with an increase of the molecular weight of PVP, leading to the growth of nanowires with higher aspect ratio.
