Abstract Well-dispersed silver nanoparticles were prepared by chemical reduction method, with polyvinyl pyrrolidone (PVP) as dispersant. The mechanisms of PVP in the preparation process were discussed through the optical characters of the reaction system. It is indicated that PVP accelerated the reaction between silver ions and glucose, because it stabilized H+. PVP compounded with Ag and protected the silver particles from growing and agglomerating. Silver particles with diameter shorter than… CONTINUE READING
