| 摘 要： | 以DMF为溶剂,合成不同n(NCO):n(OH)的聚氨酯(PU),将稀土钕盐掺入聚氨酯制得含稀土和高分子的复合材料.采用红外(FT-IR)、紫外-可见(UV-Vis)、差示扫描量热-热重分析(DSC-TGA)、荧光(FS)等手段对聚氨酯和复合材料进行了表征.红外先谱研究结果表明,钕离子与聚氨酯分子发生了作用;荧光光谱表明,复合材料发出钕的特征荧光,这为进一步研究稀土/高分子材料的性能提供了依据.

| Abstract: | In the presence of N,N-dimethylformamide solvent,the polyurethanes with different mole ratio of NCO/OH(R) were synthesized.The composites containing rare earth and polymer were also prepared through rare earth Nd compound doping polyurethanes.The polyurethane and composites were characterized by infrared spectrum(FT-IR),differential scanning calorimeter(DSC),thermal gravimetric analysis(TGA),UV-Vis spectroscopy and fluorescence measurement.The results of FTIR showed that there existed interaction between Nd... |
