摘　　要：将稀土铝酸盐长余辉发光材料充分研磨,用硅烷偶联剂对其进行包覆处理,并测试长余辉发光材料包覆前后在分散液中的分散性能及红外光谱曲线。通过湿法纺丝,制备了偶联剂包覆前与包覆后的发光海藻纤维。在电镜下观察纤维的形态结构,测试纤维的力学性能和发光性能。结果表明:经偶联剂处理后的发光材料具有更好的分散性,且包覆后的发光粉末与海藻酸原液具有更好的相容性,纺丝后形成的发光纤维具有更均匀的外貌结构,其拉伸断裂强力更大,发光强度更强,余辉寿命更长。Rare earth aluminate long afterglow luminescent materials were fully mulled and coated with si-lane coupling agent. The dispersion property and infrared spectra of long afterglow luminescent materialsbefore and after coating were measured. The alginate fibers coated before and after the coupling agent wereprepared by wet spinning. The morphology and structure of the fibers were observed under the electron mi-croscope, and the mechanical properties and luminescent properties of the fibers were tested. The resultsshowed that the luminescent materials treated by silane coupling agent had better dispersion property, andthat was coated with luminescent powder alginate solution had better compatibility with alginate solution.The luminescent fiber after spinning had a more uniform appearance, the tensile strength was stronger andhad more luminous intensity and longer afterglow.
