| 摘 要： | 以水玻璃为原料,采用硫酸制备纳米白炭黑,并利用硅烷偶联剂S i-75对纳米白炭黑进行疏水改性。通过X射线衍射、透射电镜、红外光谱和热重分析对纳米白炭黑进行表征。粉末X射线衍射（XRD）分析结果显示,纳米白炭黑为非晶态二氧化硅;通过透射电镜（TEM）分析可知,改性后的纳米白炭黑分散性更好,团聚降低,白炭黑一次粒径在20 nm-40 nm,粒子之间相互连接形成链枝结构附聚体;红外光谱（FT-IR）和热重分析（TG）显示,硅烷偶联剂S i-75成功地接枝到纳米白炭黑。活化指数（99.6%）的测定表明,合成的纳米白炭黑具有超疏水性。

| Abstract: | In this paper,the nano-silica was produced by using sulfuric acid from water-glass as raw materials and the nano-silica was hydrophobicly modified with silane coupling agent(Si-75).The silica particles were characterized with X-ray diffraction(XRD) transmission electron microscopy(TEM),fourier transform infrared analysis(FT-IR) and thermogravimetric analysis.The analysis result of powder X-ray diffraction(XRD) reveals that the nano-sicila was amorphous;TEM showed that the modified nano-silica had better sca... |
