In this study direct observations of swelling and exfoliationbehaviors on Ca-Al layered double hydroxide (LDH) and Mg-Al LDH were first carried outin distilled water, formamide solution and lauric acid solution by atmospheric scanningelectric microscopy (ASEM). LDH/calcium carbonate composites and LDH/hydroxapatitecomposites also were synthesized in solutions, and these basic data for fabrications oforganic / inorganic nano composites and laminated structures were obtained. These newapproach methods are powerful tool for direct observation of the swelling and exfoliationbehaviors of layered materials.
