As everyone knows, surfactants affect crystal growth behavior£¬different surfactants because of their different physical and chemical properties affect the solubility of reactants, reaction activity, dispersion, in particular the polar of surfactants and coordination ability  has an important implications to the morphology. In recent years,PVP as a stabilizer and structure directing agent has been successfully prepared lead and silver nanowires, nanorods, and other novel nanostructures. In our experiment, PVP may be used as cap-like agent by selective adsorption and desorption to control the growth rate of different crystal faces, thus promoting the growth of the crystal orientation and to prevent particle aggregation, stabilize the initial particles.

It is well known that the presence of surfactants   can influence the crystal growth, and different surfactants with different physical and chemical properties can influence the solubility, reactivity, and diffusion behavior of the reactants, in particular, the polarity and coordinating ability of the surfactants can influence the crystal morphology of the final product. Particularly, it is well known that the polymer PVP has been successfully employed in recent years as a stabilizing agent as well as structure-directing agent for the preparation of lead and silver nanostructures, including nanowires, nanorods and other novel nanostructures. In our experiments, the possible function of PVP and other surfactants, added as a polymer capping reagent, is to control the growth rates of different crystalline faces by interacting with these faces through absorption and desorption.
