详细研究了镁铝层状双氢氧化物（Mg-Al LDH）与各种有机表面活性剂的插层化合物的制备和表征。该制备采用再生法进行。这种有机改性的目的是制备适合于聚合物- ldh纳米复合材料的ldh。用广角x射线散射（WAXS）和傅里叶红外光谱（FTIR）对ldh -表面活性剂杂化物进行了表征。改性镁铝LDH材料的层间距离比未改性镁铝LDH材料的层间距离增加，这取决于表面活性剂阴离子的长度。有机改性后热分解变化明显。用扫描电子显微镜（SEM）观察颗粒形貌。(C) 2007年Elsevier B.V.出版
The preparation and the characterization of intercalation compounds of Mg-Al layered double hydroxide (Mg-Al LDH) and various organic surfactants have been studied in detail. The preparation has been carried out following regeneration method. The aim of such organic modification is to prepare LDHs suitable for application in polymer-LDH nanocomposites. The LDH-surfactant hybrids have been characterized by wide angle X-ray scattering (WAXS) and Fourier transform infrared (FTIR) spectroscopy. The modified Mg-Al LDH materials show an increase in interlayer distance as compared to the unmodified Mg-Al LDH depending on the length of the surfactant anions. Thermal decomposition changed significantly after organic modification. The particle morphology was investigated by scanning electron microscopy (SEM). (C) 2007 Published by Elsevier B.V.
