Abstract
In order to expand the application of biobased polycarbonate in optical components, a series of isosorbide polycarbonate (PICC)/rare earth ion complex fluorescent composites were prepared by using PICC as a macromolecular ligand and Eu3+ and Tb3+ as rare earth luminescence centers. The coordination system between rare earth ions and PICC was investigated by Fourier transform infrared spectroscopy, DSC and TGA. On adjusting the ratio of Eu3+ and Tb3+ , a PICC/rare earth ion composite with adjustable fluorescence color was obtained. Also, the thermal, mechanical and optical properties of a series of PICC/rare earth ion fluorescent films with different ratios were tested. A transparent fluorescent composite material with excellent mechanical properties and tunable fluorescent colors has been prepared. © 2024 Society of Industrial Chemistry.
掺杂铽(III)和铕(III)络合物的 PC 薄膜的综合性能
为了扩大生物基聚碳酸酯在光学元件中的应用,以 PICC 为大分子配体,Eu3+ 和 Tb3+ 为稀土发光中心,制备了一系列 PICC/稀土离子复合物荧光复合材料。通过傅立叶变换红外光谱(FTIR)、电导率稳定分析(DSC)和热重分析(TGA)对稀土离子与 PICC 的配位体系进行了研究。同时,通过调节 Eu3+ 和 Tb3+ 的比例,得到了荧光颜色可调的 PICC/稀土离子复合材料。同时,还测试了一系列不同比例的中国人保/稀土离子荧光膜的热性能、机械性能和光学性能。最终制备出了一种具有优异机械性能和可调荧光颜色的透明荧光复合材料。
