| Inorganic-organic nanocomposites have received increasing interests from Scientists in material science field for their special structure and fi.inction.They have good special properties of the organic. inorganic and nanomnaterials and are of extensive use in many science fields.For examples~ they are being used in mechanics, chemistry, optics, electrics, seperation,catalysis,biochemistry.Rare earth elements have unique properties and extensive applications owing to their special electronic configuration. Inorganic nano- CeO, coated with surfactants (oleic acid) and the nanometer-sized CeO, -PMMA composite was prepared by in situ polymerization.were discussed in this thesis and some new and meaningful results were obtained. |
