| Abstract: | Template synthesis method has been applied to our nanomaterials research widely. Colloidal soft templates are assumed to be very efficient templates for controlling the particle size and shape due to various aggregates of surfactants in water solution. The self-assemblles of surfactant in colloidal solution are also useful for preparation of non-spherical precious metal nanoparticles. In this paper, preparation methods for silver flakes are summarized, especially including the template method for preparation of nano-silver flakes. The size and shape control mechanism of template and other parameters, which also affect the size and shape of non-spherical precious metal nanoparticles, are discussed. Some suggestions are also provided for the size and shape control of nano-silver flakes. |
