【摘要】用反相胶束微乳液法制备了纳米ＣｅＯ２／聚苯乙烯杂化材料．ＸＲＤ分析表明，纳米ＣｅＯ２／聚苯乙烯杂化材料中，ＣｅＯ２是无定形粒子．ＸＰＳ分析表明，杂化材料并非简单的物理混合，ＣｅＯ２纳米粒子与有机物之间存在着一定强度的化学键．ＦＴＩＲ分析表明，ＣｅＯ２粒子的吸收存在蓝移现象．更多还原

【Abstract】 Nanometer-sized CeO2/polystyrene hybrid material was prepared using reversed micelles mi- croemulsion method. XRD analysis revealed that the CeO2 nanoparticles in polystyrene were amorphous. XPS patterns indicated that the hybrid material was not a simply physical mixture, but a certain strength of chemical bond between CeO2 nanoparticles and polystyrene existed. FTIR patterns revealed that the absorption of Ce-O bond in hybrid material was blue-shifted.更多还原
