Nano-silver sol was prepared using sericin as reducing agent and dispersing agent, which was extracted from cocoons with sodium carbonate (Na2CO3) degumming method. The products were character-ized by ATR-FTIR, TEM and UV-vis. The effects of sericin dosage, silver nitrate concentration, pH, reaction temperature and time on the formation of nano-silver sol were studied. The results showed that the nano-sil-ver sol prepared by extracted sericin Ⅲ had the best properties. Spherical nano-silver particles were obtained and the proper technology of preparing nano-silver sol was that 15 mL of sericin Ⅲ extracted solution, 4 mL silver nitrate solution (2 g/L) and reacted at 90℃for 30 min under pH=9~11.
