含稀土光学树脂的制备和性能研究

稀土高分子材料是通过稀土金属与高分子的复合而制备的一类兼具稀土光、电、磁等特性和高分子质轻、抗冲击和易加工等优良综合性能的功能材料。稀土高分子材料主要分为两大类型:一类是稀土化合物作为掺杂剂均匀分散到高分子的单体和聚合物中;第二类是稀土化合物以单体形式参与聚合或缩合以及稀土化合物配位在聚合物的侧链上获得的键合型稀土高分子材料。本文综述了国内外在稀土金属与高分子复合材料方面的研究进展及相关应用,介绍了本组在合成含稀土化合物和配合物光学树脂方面的研究情况,通过把稀土配合物复合到苯乙烯和甲基丙烯酸共聚体系中,获得了发光强度高、荧光寿命长、透光率高、机械性能好的光学树脂,并对今后工作方向进行了展望。

Synthesis and Properties Studies of Optical Resins Containing Rare Earth

Composite materials of rare earth metals and polymers are a series of functional materials with many excellent properties and potential application. This review presents the research state over the decades on the preparation of polymers containing rare earth metals in doping-type and bonding-type, and its applications on the fields of optics, electricity, magnetic, catalysis, analysis, etc. The rare earth compounds were uniformly dispersed into monomers and polymers as dopant in doping type rare earth polymer, while the bonding type rare earth polymers could be synthesized by the following three approaches:In the first approach, lanthanide ions were incorporated with the reactive functional groups such as hydroxyl and carboxyl in the polymer side chains; The second one is that lanthanide ions were coordinated with polymer dentate ligands such as β-diketonates, carboxyl, pyridine, porphyrin and sulfo group; The third one is homopolymerization and copolymerization of the monomers containing lanthanide ions. In addition, some research results in our groups on the synthesis and properties of optical resins containing rare earth compounds were summarized. In our recent work, some binary and ternary rare earth complexes were dispersed into the styrene/methylacrylic acid copolymerization system, and the optical resins possess a high transparency, intense luminescent properties and good mechanical properties were obtained.
