摘　　要：Surface reactable modified silver nanoparticles were prepared by NaBH4 reduced silver ion in the aquenous solvent, in the presence of the double group modifying agent, O,O′-di(11-bromic undecane)dithiophosphonic acid. The morphology and structure of the product were characterized using Transmission Electron Microscope(TEM), UV-Visible Absorption(UV-Vis) spectra, Fourier Transform Infrared(FTIR) spectra. The result indicate that the products are spherical shape and no aggregation, C-Br functional groups are on the outermost portion of the silver nanoparticles. The nanoparticles were well dispersed in organic solution, such as chloroform, petroleum ether, toluene etc. The analysis of the sample which reacted with trimethylamine by X-ray photoelectron spectra(XPS) shows the silver nanoparticles can undergo many reactions.Surface reactable modified silver nanoparticles aquenous solvent, in the presence of the double group were prepared by NaBH4 reduced silver ion in the modifying agent, O,O＇-di（ll-bromic undecane）dithiophosphonic acid.
