摘　　要： 采用一步水热法合成人工纤蛇纹石-硅酸镁纳米管,再进一步通过原位氧化聚合法在硅酸镁纳米管表面负载聚苯胺(PANI)纳米纤维,制得聚苯胺-硅酸镁(PANI/MSNTs)纳米复合材料。利用傅里叶红外变换光谱仪(FTIR),热重分析(TGA)、X射线衍射(XRD)等对纳米复合材料进行表征。结果表明:PANI/MSNTs纳米复合材料具有较高的胺基官能团密度和良好的热稳定性能,可作为固体胺吸附剂用于大气中CO2的吸附分离。 Magnesium silicate nanotubes, as a synthesized chrysotile-type mineral, were synthesized by hydrothermal method. The Mg3Si2O5（OH）4 nanotubes （MSNTs） were further modified to obtain PANI/MSNTs nanocomposites by grafting of polyaniline（PANI） nanofiber via in situ oxidation polymerization. The as-synthesized functional nanocomposites were characterized by Fourier transform infrared spectroscopy （FTIR）, X-ray diffraction （XRD）, thermogravimetric analysis （TGA）. The results showed that the PAN1/MSNTs nanocomposites have higher amino density and excellent thermal stability, and exhibited great impetus to be utilized as a highly efficient nanosorbent for the CO2.
