Abstract

<p>Recently, swelling and delamination of Layered double hydroxides (LDHs) attract attention for future nano architechnology. The evaluations of swelling and delamination behaviors principally have been carried out using the dry sample by transmission electron microscopy (TEM), powder X-ray diffraction method (XRD) and atomic force microscopy (AFM). But these analyses are not suitable for direct observation of LDHs in solution. In this study, direct observation of swelling and delamination behaviors of LDHs were first carried out in distilled water, sodium laurate solution and formamide solution by Atmospheric Scanning Electron Microscope (ASEM). This new approach method is powerful tool for direct observation of the swelling and delamination behaviors of LDHs in solution.</p>
