| 摘 要： | 采用硅烷偶联剂对纳米二氧化钛进行表面处理,以改性纳米二氧化钛和有机硅中间体为种子乳液,以过硫酸钾为引发剂,甲基丙烯酸甲酯(MMA)、甲基丙烯酸丁酯(MBA)为主要共聚单体,通过原位聚合反应,合成纳米TiO2-硅丙复合乳液。采用红外光谱、透射电镜(TEM)、激光粒度分布等手段,对所制备的纳米TiO2-硅丙复合乳液进行了表征,证明所得产品是硅氧烷和丙烯酸酯的共聚物,具有核/壳结构,且乳液粒径分布较窄,平均粒径在63 nm左右。

| Abstract: | The nanometer TiO2 was modified by silane coupling agent.With the modified TiO2 and silicone intermediate as seed emulsion,the methyl methacrylate(MMA),methyl butylacrylate(MBA) as the main monomers,the potassium peroxydisulfate as initiator,the nano TiO2/silicone-acrylate core/shell emulsions were prepared by in situ emulsion polymerization.The nano TiO2/silicone-acrylate copolymer was characterized by infrared spectroscopy,transmission electron microscopy(TEM) and laser particle size distribution.The product was determined as a silicone-acrylate copolymer with a core/shell structure and an average particle size about 63 nm. |
