Sb 2 O 3 nanoparticles were prepared via hydrolyze reaction of SbCl 3 in water - ethanol solution,and were char - acterized by XRD and TEM.In addition,the effect of reactive condition on particle size was also investigated systematically.When the sample modified by coupling agent was applied in formulation of plastic,the mechanical property and flame retardancy was better than micron sample.
Composite microspheres composed of monodispersed poly（St-co-MAA） latices with diameter about 260 nm as core and Ag nanocrystals as shell were prepared by an in situ reduction method. The shell thickness could be controlled in the range of 15--45 nm by this coating process. The structure and the composition of the core-shell microspheres were characterized by transmission electron microscopy （TEM）, X-ray diffractometry （XRD）, X-ray photoelectron spectroscopy （XPS）, and thermogravimetric analysis （TG）. The formation of the composite microspheres is explained by the nucleation of silver on the surface of the latices followed by growth of the silver shell.
