英文摘要	In this paper, we reported a two-step technique for fabrication of PMMA/Ag nano coreshell structure with well-established processing parameters and an ease control. Firstly, we fabricated the monodisperse PMMA nanospheres with a diameter of about 170 nm by emulsifier-free emulsion polymerization. Then, we modified the PMMA nanospheres surface with (3-methacryloxypropyl) trimethoxysilane(MATS) and (3-mercaptopropyl) trimethoxysilane(MPTMS), resulting in a uniform sulfhydryl (SH)-group modified outlayer and Ag nanoparticles further grew on the modified surface of PMMA nanospheres with an effective interaction between sulfhydryl(SH) groups and Ag+. In doing so, finally we synthesized PMMA/Ag core-shell composited nanoparticles. The structure of the synthesized sample was investigated by scanning electron microscopy (SEM), transmission electron microscopy(TEM) and UV-Vis extinction spectra. The results indicate that the well-dispersed PPMA/Ag core-shell nanoparticles with uniform particle size distribution were successfully fabricated using this improved technique.
