| 摘要: 本文将磁性基质与镁铝水滑石进行组装首次合成出一种新型的纳米磁性功能材料—磁性纳米镁铝水滑石。这种新型纳米功能材料的XRD及TA结果表明,镁铝水滑石赋予磁性后并没有改变其层状结构的典型特征。样品的TEM图表明,磁性基质的加入后样品的颗粒粒径并没有明显增大,且保持在20～50nm之间。对磁性镁铝水滑石磁性能的考察结果表明,样品的比饱和磁化强度随磁性基质含量的增加而线性增加。 |

| Abstract: In this report, magnetic particles were assembled in Mg-Al hydrotalcites for the first time, and we synthesized magnetic nanometer-sized Mg-Al hydrotalcites, results of XRD and TA of which showed that the addition of mag-netic substrates didn＇t changed the typical character of layered-structure. By TEM photos of samples,we may find that after magnetic substrates added ,particle size of samples didn＇t obviously enlarged,and remained between 20nm and 50nm. Magnetic properties of magnetic Mg-Al hydrotalcites were studied by Vibrating-sample Magne-tometer(VSM) and the results showed specific saturation magnetization of samples increased linearly with the content of magnetic particles. |
