Abstract : Nanocomposite of zinc layered hydroxide-3-(4-methoxyphenyl) propionate (ZLH-MPP) were prepared by intercalation of 3-(4-methoxyphenyl) propionic acid (MPP) into the interlamellae of zinc layered hydroxide (ZLH) by using direct reaction of an aqueous suspension of zinc oxide with MPP solution via one step method. Power x-ray diffraction patterns showed the result of successful intercalation of ZLH-MPP nanocomposite at 27.3 Ã… at a low angle of reflection. The result was also supported by FTIR spectra and elemental analysis of the nanocomposite. On the basis of EDX and TGA-DTG results, the chemical formula of ZLH-MPP nanocomposite was Zn(OH)1.47(CH3OC6H4CH2CH2COO-)0.53.0.87H2O). The controlled release of MPP from interlayer of ZLH-MPP nanocomposite showed that phosphate medium yielded the highest percentage release compared to sulphate and chloride medium. The release of MPP was found to be in controlled manner governed by pseudo-second order for phosphate medium and first order for sulphate and chloride medium.
