This study aims to synthesise magnesium layered hydroxide-3-(4- methoxyphenyljpropionate (MLH-MPP) and coated nanocomposites for controlled release formulation of herbicide. Direct reaction method has been used to intercalate MPP into the space between layers of MLH. Further, carboxymethyl cellulose (CMC) and chitosan, was coated on the external surface of the MLH-MPP nanocomposite to form new materials, named MLHMPP/ CMC and MLH-MPP/chitosan nanocomposites, respectively. The physicochemical properties of all nanocomposites were characterised using powder x-ray diffraction (PXRD), Fourier transform infrared spectroscopy (FTIR), carbon, hydrogen, nitrogen and sulphur (CHNS) analyser, inductive coupled plasma optical emission spectrometry (ICP-OES), thermogravimetric analysis and derivative thermogravimetry (TGAlDTG), field emission scanning electron microscope (FESEM) and transmission electron microscope (TEM). Results of this study showed that the XRD pattern revealed an intense and sh.....
