摘要
以偕胺肟纤维为基体纤维,与三氯化钐溶液反应,生成偕胺肟-钐(Ⅲ)配合物纤维,用扫描电子显微镜观察偕胺肟-钐(Ⅲ)配合物纤维的形貌.研究偕胺肟-钐(Ⅲ)配合物纤维的荧光性质,结果显示:在eλx=300 nm激发波长下,偕胺肟-钐(Ⅲ)配合物纤维在475 nm处出现荧光发射峰,且随配合物纤维中钐含量的增加而发生改变.对不同钐含量的配合物纤维样本进行了力学性能测试,并与原纤维(PAN)、偕胺肟纤维进行了比较.找出了荧光强度强、力学性能好的钐含量配合物纤维的最佳工艺条件,为荧光纤维的实际应用提供理论依据.
Chelating fiber containing amidoxime group-Samarium complex was prepared by the reaction of Chelating fiber containing amidoxime group with Smcl3,the complex SEM.the fluorescence properties of fiber was researched,and their surfacial shape was observed by SEM.At the excitation wavelength of 300nm,the emission peak of fluorescence appeared at 475nm,and it was changed by content of Sm3+.The mechanic performance of Chelating fiber containing amidoxime group-Samarium complex was tested,and compared with PAN and...
