摘　　要：在室温下,以SrCl2.6H2O和(NH4)2CO3为原料,采用咪唑季铵盐离子液体表面活性剂1-十六烷基-3-甲基咪唑溴盐[C16mim]Br软模板法制备了SrCO3纳米棒。利用透射电子显微镜(TEM)对产物进行了表征。初步探讨了SrCO3纳米棒的形成机理。结果表明SrCO3纳米棒长度在200nm左右,由平均直径为10-20nm的纳米粒子组成,论文该制备方法简便、温和、快速、环境友好,具有一定的应用前景。This paper has reported the preparation of strontium carbonate nanorods using SrCl2·6H2O,（NH4）2CO3 in micelles formed by the ionic liquid surfactant,1-hexadecyl-3-methylimidazolium bromide（[C16mim]Br）,as soft template at room temperature.The size and morphology of SrCO3nanorods were characterized by transmission electron microscopy（TEM）.The results showed that the length of SrCO3 nanorods was about 200nm,the average diameter of SrCO3 nanorods was about 10-20nm.The formation mechanism of strontium carbonate nanorods was discussed primarily.The method developed in this work was convenient,mild,fast and environmentally friendly.
