摘要: 采用硅烷偶联剂对稀土发光材料进行表面改性。将甲基丙烯酸甲酯、改性后的稀土发光材料和引发剂加入到聚合反应装置中,进行原位乳液聚合,制备聚甲基丙烯酸甲酯(PMMA)基稀土发光母料。红外光谱、热失重、扫描电镜分析表明,PMMA已经成功接枝到稀土发光材料表面,并以片状均匀地包覆于稀土发光材料表面。荧光光谱分析表明,乳液聚合过程中PMMA基稀土发光母料没有改变稀土发光材料的基质,PMMA基稀土发光母料的发光中心与稀土发光材料的相同,激发波长在可见光范围之内。

Abstract: Rare earth luminescent material was modified with silane coupling agent, which was further encapsulated with a layer of poly(methyl methacrylate )(PMMA) via in-situ emulsion polymerization. FTIR, TG and SEM showed that PMMA was uniformly grafted on the surface of rare earth luminescence materials forming a thin layer. Such PMMA coated rare earth luminescence materials maintained good fluorescence performance and their original luminescence centers.
