| 摘 要： | 在乙醇—水体系中,用硬脂酸作为表面修饰剂,用一步合成法制备了具有硬脂酸修饰的纳米BaSO4.用傅立叶红外(FT-IR),粉末X衍射(XRD),动态光散射(DLS),透射电镜(TEM),热重分析(TGA)等测试方法对所制得的纳米BaSO4进行了表征,结果表明,在加入一定量的硬脂酸和少量的氨水的条件下,能得到分散性好,平均粒径为16nm的具有硬脂酸修饰的球形BaSO4.

| Abstract: | In this paper,we prepared nanosized BaSO_(4) particles modified with stearic acid in ethanol-water reaction system,and obtained the optimal reaction condition.The nanoparticles were characterized by Fourier transform infrared spectroscopy(FT-IR),powder X-ray diffraction(XRD),transmission electron microscope(TEM),dynamic light scattering(DLS) and thermo gravimetric analysis(TGA),respectively.The results indicated that the BaSO_(4) with the average diameter of 16nm modified with stearic acid having good dispersion in the presence of a certain concentration NH_(3)·H_(2)O and stearic acid. |
