Fine polymer particles coated with electrically conductive powder were prepared by material recycle of expanded polystyrene. Two types of composite polymer particles were prepared ; one which solid powders are dispersed in the interior, other which the surface is coated with solid powders.As the solvents dissolving expanded polystyrene, di-chloro methane and limonene were adopted. In the experiment, the added amounts of magnetite and titanic oxide powders and the addition time were changed stepwise.It was found that polymer particles coated with solid powders were prepared when powders were added into the continuous water phase.Moreover, the optimum operation to prepare the functional particles by material recycle of expanded polystyrene was established.

通过回收发泡聚苯乙烯材料，制备了包覆导电粉末的聚合物细颗粒。采用二氯甲烷和柠檬烯作为溶解发泡聚苯乙烯的溶剂，制备了内部分散有固体粉末和表面包覆有固体粉末的两种复合聚合物粒子。实验中，通过改变磁铁矿粉和二氧化钛粉的加入量和加入时间，发现在连续水相中加入粉料，可制备出包覆有固体粉料的聚合物粒子，并确定了利用发泡聚苯乙烯回收料制备功能粒子的最佳操作条件。
