Civil engineering (General) <p>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 sharp peak with basal spacing of 18.9 A, which is proved that MPP anions were successfully intercalated into the space between layers of MLH in a monolayer arrangement. The XRD pattern for both coated nanocomposites indicates the adsorption of the polymer on the surface of MLH-MPP nanocomposite. TGAlDTG spectra have shown an increase in the thermal stability of the MPP anion in all nanocomposites. Both coated nanocomposites showed a slower controlled release compared to the MLH-MPP nanocomposite and the release behaviours of MPP anion from all nanocomposites were controlled by the pseudo-second order kinetics. In conclusion, the MLH-MPP and coated nanocomposites have been successfully synthesised and can be used as a host for the controlled release formulations of herbicide. The implications from these results highlight the potential of the nanocomposite as encapsulation materials for controlled release formulations of herbicide in the agriculture sector.</p> 2017 thesis https://ir.upsi.edu.my/detailsg.php?det=3077 https://ir.upsi.edu.my/detailsg.php?det=3077 text eng closedAccess Masters Universiti Pendidikan Sultan Idris Fakulti Sains dan Matematik N/A
