1 | 2015 thesis | Synthesis and characterization of layered metal hydroxide-3-(4-hydroxyphenyl)propionate nanocomposites for controlled release formulation Siti Nurasikin Ahmad The aim of this research is to synthesize and characterize the nanocomposites and also to determine the controlled release behaviour of 3-(4-hydroxyphenyl)propionic acid (HPP) anion. Zinc layered hydroxide-3-(4-hydroxyphenyl)propionate (ZLH-HPP) nanocomposite was synthesized by direct reaction method. Meanwhile, layered double hydroxide-3-(4 hydroxyphenyl)propionate (LDH-HPP) nanocomposite was synthesized by ion-exchange method. The ZLH-HPP and LDH-HPP nanocomposites physicochemical properties was characterized using powder x-ray diffraction (PXRD), Fourier transform infrared spectroscopy (FTIR), carbon, hydrogen, nitrogen, oxygen and sulphur analysis, inductive coupled plasma-optical emission spectrometer, thermogravimetric analysis and derivative thermogravimetry, and field emission scanning electron microscope. Research findings confirmed that two nanocomposites ZLH-HPP and LDH-HPP were successfully synthesized with PXRD pattern of ZLHHPP and LDH-HPP nanocomposites show well order l..... 5992 hits |
