摘要 以尿素为沉淀剂,采用均匀沉淀法,制备得到两种有机插层水滑石Zn2Al-LDH/PNCA和Zn2Al-LDH/PHBA化合物,并用XRD、FT-IR和UV-VIS对合成的化合物的结构和性质进行了测定。结果表明合成的有机插层水滑石具有良好的层状结构;其紫外光谱与有机物进行对比,有机物插层后紫外吸收能力增强。 Take urea as a preeipitiant, Zn2A1-LDI-I/ PNCA and Zn2A1-LDH/PHBA are successfully synthesized by a homogeneous precipitation method. The samples thereby obtained are characterized by XRD, FT-IR and UV-VIS. The results show that Zn2A1-LDH/PNCA and Zn2A1-LDA/PHBA has a good layered structure. TheUV-VIS results indicate that the UV- properties are enhanced after LDHs are intercalated with organic.
