Abstract:

In this paper, 2 - (2 - hydroxy - 5 - sulfonic acid-phenyl) -5 - amino-2H-benzotriazole had been inserted into the precursor layer by ion exchange method using Mg/Zn/Al-CO3-LDHs as precursor. The samples obtained were characterized by XRD, SEM, laser particle size analyzer, IR, UV spectra and TG-DTA. The results show that, by controlling the conditions, the CO32- ions of precursor layer can be replaced by HASB, producing strong supramolecular interaction between the main bodies. The material was obtained in the ratio of MgZn2Al, can achieve the UV absorption maximum and better thermal stability, resulting in a new type of inorganic - organic composite supramolecular UV shielding materials.
