Assembly, Characterization and Ultraviolet Properties of Sulfosalicylic Acid Intercalated Mg/Cu/Zn/Al-LDHs

Sulfosalicylic acid intercalated Mg/Cu/Al-LDHs composite material was prepared by coprecipitation method. The as-prepared material was characterized by XRD, FT-IR and TG-DTA measurements. It was found that the object was intercalated into LDHs layers and the layer distance changed from 0.832 nm to 1.125 nm. Based on these data, a structure model about the LDHs layers was speculated. EDS analysis verified that the element ratio of interca- lated LDHs was close to the theoretical value and the LDH excellent layer structure was maintained after intercalating assembly. Furthermore, the thermal stability of LDHs was improved due to the effects of electrostatic and hydrogen bond between the object and basal planes. Meanwhile, it was indicated by UV-DRS results that the intercalated LDHs composite show both shielding and absorbing effects to UV light.
