| 摘 要： | 以葡萄糖水溶液为反应介质,在氧化钙消化成氢氧化钙的过程中,加入苯乙烯单体和引发剂,采用原位悬浮聚合法成功制备了聚苯乙烯(PS)包覆氢氧化钙Ca(OH)2]形成Ca(OH)2/PS微球.考察了葡萄糖水溶液、苯乙烯、稳定剂聚乙烯醇以及反应温度对单分散Ca(OH)2/PS微球的粒径及粒子分散系数的影响,得出较佳合成条件.在较佳条件下制备的Ca(OH)2/PS微球平均粒径为30～40 μm,粒子分散系数为0.08～0.10.扫描电镜照片表明,Ca(OH)2/PS具有良好的球形度,表面光滑、无破损.红外光谱表征显示,产物为Ca(OH)2/PS微球.

| Abstract: | Polystyrene(PS) coated calcium hydroxideCa(OH)2],namely Ca(OH)2/PS microspheres were successfully prepared by in-situ suspension polymerization method through adding initiator and styrene monomer into glucose - aqueous media when calcium oxide (CaO) turning into Ca(OH)2.Effects of glucose - aqueous solution,styrene,stabilizer-polyvinyl alcohol (PVA),and reaction temperature on particle size and dispersion coefficient of monodisperse Ca(OH)2/PS microspheres were investigated and optimal synthesis conditions were obtained.Ca(OH)2/PS microspheres with average particle size of 30～40 μm and particle dispersion coefficient of 0.08～0.10 were obtained under optimal conditions.SEM photos showed that Ca(OH)2/PS has good sphericity,smooth surface and no damage.Infrared spectroscopy (FT-IR) indicated that the products were Ca(OH)2/PS microspheres. |
