| Abstract: | A new method for the preparation of poly(methyl methacrylate)/Ce(OH)_3-Pr_2O_3/graphite nanosheets ternary phase nanocomposites is developed.Graphite nanosheets(NanoG) are prepared by treating the expanded graphite with sonication in aqueous alcohol solution.The new ternary phase nanocomposites are prepared via in situ polymerization of MMA monomer in the presence of graphite nanosheets and Ce(OH)_3-Pr_2O_3 through reverse micelle template,in which the methyl methacrylate(MMA) is designated as oil phase.The nanocomposites are then dispersed in chloroform and coated on glass slides to form films.Scanning electron microscopy(SEM) and transmission electron microscopy(TEM) are used to characterize the structure and nanoscale dispersion of the graphite nanosheets and the nanocomposites.From the thermogravimetric analysis,the introduction of graphite nanosheets and inorganic nanopartices exhibite a beneficial effect on the thermal stability of PMMA. |
