采用在位分散聚合法制备了纳米CeO2/PMMA杂化材料。XRD分析表明，杂化材料 是无定形的。SEM分析表明，杂化材料中CeO2含量不同，材料的断面形貌明显不同 ，随CeO2含量的增加，杂化材料由韧性断裂向脆性断裂转变。EDS面分析表明，Ce 在杂化材料中分布均匀。实验表明，随CeO2含量的增加，杂化材料的透过率与溶解 性降低。

The nanometer-sized CeO_2/PMMA hybrid material was prepared by in- situ polymerization method. XRD pattern shows that the hybrid material is amorphous. SEM indicates that the morphology of fracture plane of the hybrid material is different when CeO_2 content varies in the hybrid material, the tenacity fracture of hybrid material changes into fragility with the the increase of CeO_2 content. EDS reveals that the distribution of Ce in the hybrid material is uniform. It is found that the transmissivity and solubility of the hybrid material decrease with the increase of CeO_2 content.
