一种稀土荧光纤维的制备与性能研究

Study on synthesis and properties of rare earth fluorescent fiber

合成了含有苯环和羧基的有机稀土纳米发光体,并通过熔融纺丝制备出了聚丙烯荧光纤维.通过红外光谱、元素分析、透射电镜照片、荧光光谱、DSC和TGA曲线等,对有机稀土纳米发光体和稀土荧光纤维的组成、结构和性能进行了表征.结果表示,有机稀土纳米发光体具有稳定的组成和结构,优异的热性能和荧光性能;电镜照片显示其直径为40～50 nm.有机稀土纳米发光体在聚丙烯中良好的分散性,也不影响其优异的荧光性能和热性能.

The organic-nano rare earth light conversion agent （ONRELCA） with benzenoid and carboxyl structure was synthesized. The polypropylene （PP） fluorescent fiber with the ONRELCA was prepared. The composition, structure and properties of the ONRELCA were characterized through the IR spectra, element analysis data, TEM photos, fluorescent spectra, DSC and TGA curves. The results show that the ONRELCA possesses of stable composition and structure, excellent thermal and luminescent properties. The TEM photos indicate that the particle diameter of the ONRELCA is 40-50 nm. This endues the ONRELCA in PP with favorable dispersible property. The polypropylene fiber with the ONRELCA has excellent luminescent property.
