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.

关键词: Ce, CeO2, 纳米粒子, 苯乙烯, 杂化材料

Abstract: Nanometer-sized CeO2/polystyrene hybrid material was prepared using reversed micelles microemulsion 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.
