摘要：
Cinnamate/layered double hydroxide (LDH) composites were prepared by a reconstruction method using sodium cinnamate solution. The cinnamate solution of 100 mM was the most remarkable condition to obtain high cinnamate content of the cinnamate/LDH composite. The composite included about 30 mass % of cinnamate was prepared using the LDH with Mg/Al = 2. In this composite, the new interlayer observed in XRD at 2 theta = 4.5 degrees formed a bilayer configuration of cinnamate. This composite showed excellent UV absorbability in UV-B region. Although the interlayer cinnamate changed into a dimer structure after UV radiation, the original UV absorbability was maintained in the composite. (C)2013 The Ceramic Society of Japan.
