摘 要：As functional polymer materials,monodispersed polystyrene microspheres with microns size could be assembly into photonic *** are of wide prospects for using in many fields such as template materials,optical filer materials, light switch,high-density electromagnetic data storage and chemical and biological chemical sensors,*** monodisperse micron-size polystyrene particles were prepared by emulsifier-free emulsion *** effects of styrene,potassium persulfate concentration and stir velocity on the average diameter of polystyrene and its distribution were mainly *** results showed that with the increasing of concentration of potassium persulfate,particle size *** the increasing of concentration of styrene and stir velocity,particle size increased firstly and then decreased. When the concentration of potassium persulfate was 1.0 mg/ml,the concentration of styrene was 0.08 g/mL and stirring velocity was 230 r/min,size of polystyrene particles were 1.4μm and standard deviation was *** of synthesized products and FT-IR contrastive analysis showed that polystyrene was prepared.
