摘要/Abstract

摘要： 本文以氧化铽（Tb₂O₃）、甲基丙烯酸（MAA）、水杨酸（HSal）、肉桂酸（HCA）和邻菲罗啉（Phen）为原料，制备了Tb（MAA）₃ Phen、Tb（Sal）₃ Phen和Tb（CA）₃ Phen探针分子，并将探针分子分别加入甲基丙烯酸甲酯（MMA）中，在过氧化苯甲酰（BPO）引发下聚合，制得3种温敏漆样品。采用红外光谱仪、荧光光谱仪和扫描电子显微镜，对探针分子的结构、发光性能、形貌和温敏漆的温度猝灭性能进行了表征，研究了不同配体对探针分子发光性能和温敏漆温度猝灭性能的影响。红外光谱表明成功合成了Tb（MAA）₃ Phen、Tb（Sal）₃ Phen和Tb（CA）₃ Phen探针分子；扫描电镜照片显示Tb（MAA）₃ Phen、Tb（Sal）₃ Phen和Tb（CA）₃ Phen的微观形貌分别为不同三斜棒状和不规则层状；荧光光谱表明Tb（MAA）₃ Phen具有最佳的发光性能，相应的温敏漆在25~65℃范围内具有良好的温度猝灭性能和灵敏度。

Abstract: Probe molecules of Tb(MAA)₃ Phen, Tb(Sal)₃ Phen and Tb(CA)₃ Phen were prepared by using terbium oxide (Tb₂O₃), methacrylate (MAA), salicylic acid (HSal), cinnamic acid (HCA) and phenanthroline (Phen). A series of temperature sensitive paints were obtained by the polymerization of different probe molecules, methyl methacrylate(MMA) and the initiator of benzoyl peroxide(BPO). The structure, morphology, luminescence property of probe molecules and the temperature quenching property of temperature sensitive paints were characterized by infrared spectrometer, fluorescence spectrometer and scanning electron microscopy. The effect of different ligands on the luminescence property of probe molecules and the temperature quenching property of temperature sensitive paints were studied. It is indicated that Tb³⁺ and primary ligands were coordinated and Phen was involved in. It is demonstrated that terbium with phenanthroline ternary complex of MAA as primary ligand has the best luminous performance. Temperature sensitive paints have favorable temperature quenching properties at the temperature range of 25-65℃ is illustrated. It is analyzed that the temperature sensitive paint based Tb(MAA)₃ Phen has a better application value comprehensively.
