中文摘要: 通过一步法绿色合成了CdSe-聚氨酯（CdSe-PU)纳米复合发光材料。在N2保护下，将单质硒（Se）溶于蓖麻油，以蓖麻油酸作为氧化镉（CdO）的配体，合成硒化镉（CdSe）纳米晶。将聚丙二醇2000和异佛尔酮二异氰酸酯(IPDI)合成的预聚体，加入含CdSe纳米晶的蓖麻油溶液，通过交联作用得到CdSe-PU纳米复合发光材料。采用紫外-可见分光光度计（UV-Vis）、荧光光谱仪（PL）、傅里叶红外光谱仪（FT-IR）、热重分析仪(TGA)、透射电子显微镜(TEM)对CdSe纳米晶和聚氨酯复合材料的结构和性能进行了表征。结果表明：此方法合成的CdSe纳米晶性能良好，能在聚氨酯纳米复合材料中均匀分散且性能稳定，CdSe-PU纳米复合材料耐热性有所提高。
Abstract:A one-step green synthetic route to prepare CdSe-polyurethane(CdSe-PU) nanocomposites with luminescence was successfully established using natural products, castor oil and its corresponding acid, ricinoleic acid. Firstly, cadmium selenide (CdSe) nanocrystallines were prepared by single selenium (Se) dissolved in castor oil reacting with cadmium oxide (CdO) with ricinoleic acid as ligand under N2 protection. And then the polyurethane prepolymer which was synthesized with polypropylene glycol 2000 and isophorone diisocyanate (IPDI) was added for further cross-linked copolymerization. Finally, the film of CdSe-PU nanocomposites with luminescence was obtained after cured in a mold. The structure and properties of CdSe nanocrystallines and CdSe-PU nanocomposites were characterized by UV-Vis, PL, FT-IR, TGA, TEM. Results showed that the CdSe nanocrystallines had good morphology and fluorescence, which dispersed well ana maintained as well in PU nanocomposites. The heat resistance of CdSe-PU nanocomposites was improved.
