Abstract
The present invention relates to a process for the preparation of a thermally treated composite of Zn-Al layered double hydroxide. The present invention particularly relates to the incorporation of Cu(II) in the Zn-Al layered double hydroxide to make it antibacterial. Copper (II) is present as Cu4(OH)6S04 and distributed throughout being an integral part of the matrix. The aforementioned Cu-LDH composite was found to be showing antibacterial activity against pathogens like E.coli and S.aureus. Calcined product of copper LDH composite at 800°C was also found to be showing antibacterial effect against the same pathogens.
