摘　　要：以尿素为沉淀剂,用均匀沉淀法一步合成Zn2Al-LDHs/对苯二甲酸和Zn2Al-LDHs/间苯二甲酸,利用XRD、IR与UV对所得到的有机物插层水滑石材料的组成、结构和性质进行分析与表征。结果表明,合成的两种有机物插层水滑石样品具有典型的水滑石结构,有机物分子在层间以双层交错的形式排布。紫外漫反射光谱图研究表明所合成的两种二元羧酸插层水滑石在UVB段有很好的紫外吸收性能。By using urea as precipitating agent,Zn2Al-LDHs / p-Phthalic acid; Zn2Al-LDHs / m-Phthalic acid are successfully synthesized by the homogeneous precipitation method. The composition,structure and properties of the obtained organics intercalated layered double hydroxides materials are analyzed and characterized. The result shows that the two synthetic organics intercalated layered double hydroxides samples have typical hydrotalcite structure,and the organic molecule is distributed in interlamination with the form of bilayer arrangement. The study of ultraviolet diffuse reflection spectrogram shows that the two synthetic dicarboxylic acid intercalated layered double hydroxides have good ultraviolet absorbency for UVB segment.
