| 摘 要： | 提出一种将多壁碳纳米管碘化后制备银/多壁碳纳米管（Ag/MWCNTs）复合材料的方法。通过球磨对碘化多壁碳纳米管进行了功能化，并通过透射电子显微镜（TEM）、X射线衍射（XRD）、傅里叶变换红外光谱（FT-IR）、拉曼光谱和热重分析（TG）对其进行了表征。结果表明，经碘化处理后，银纳米粒子（Ag-NPs）能更好地粘附在碳纳米管表面，改善了银纳米粒子与碳纳米管之间的连接。羟基（-OH）基团的伸缩振动明显增强，激活了碳纳米管的表面，增加了碳纳米管表面Ag+形核的数量。在260 ℃以下，Ag/MWCNTs复合材料的质量损失小于MWCNTs的质量损失。最后，制备了银-环氧树脂浆料，发现使用Ag/MWCNTs复合物制备的浆料具有最低的电阻率和最高的热导率。

| Abstract: | A method was developed for preparing silver/multi-wall carbon nanotubes (Ag/MWCNTs) composites after iodination of the MWCNTs. The MWCNTs were functionalized by ball milling in the presence of iodine, and characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy, and thermogravimetric analysis (TG). The results show that the silver-nanoparticles (Ag-NPs) adhere better to the surface of the MWCNTs after iodination, which can improve the connection between the Ag-NPs and the MWCNTs. The hydroxyl (-OH) group stretching vibration is clearly enhanced, which activates the surface of the MWCNTs and increases the number of Ag+ nucleation sites on the surface of the MWCNTs. At temperatures lower than 260 °C, the mass loss of Ag/MWCNTs composite is less than that of MWCNTs. Finally, three silver-epoxy resin pastes were separately prepared, and the paste prepared using the Ag/MWCNTs composites has the lowest resistivity and the highest thermal conductivity. |
