Abstract:	This study used UV-irradiated silver chloride to act as seed crystals, employed the polyol synthesis method to synthesize silver nanowires in the wide temperature range of 120 C160 C, and investigated the growth mechanism of silver nanowire. The growth process of silver nanowires can be divided into three regions: region I is controlled by a mixed diffusion model involving Case I diffusion and Case II diffusion, where the activation energy needed for Case I and Case II diffusion is approximately 192 KJ/mol and 50 KJ/mol. Significant one-dimensional anisotropic growth occurs in region II, and the growth rate in this region is faster than in region I. In region III, because the {111} crystal plane of the silver nanowires has gradually been coated by PVP, the growth rate will approach saturation.
