Abstract: Allopurinot intercalated Zn/Al-NO3-LDH composite materials were prepared by coprecipitation and ion exchange methods. It was found by XRD, FT-IR and TG-DTA analysis that allopurinol were intercalated into the LDH layers and formed a supramolecular structure in the reaction with laminate. The structure could improved allopurinol acid resistance and thermal stability. The allopurinol intercalated LDH preparaed by coprecipitation method has an excellent sustained-release performance. It was supposed that the intercalation capacity of organic molecules was increased by a Sol-Gel intermediate which was easy for the objects to be ion-exchanged and embedded during the organic molecules intercalating into the LDH layers by coprecipitation method.

Key words: allopurinol, LDH, intercalating assembly, composite, sustained-release
