聚丙烯荧光材料制备及其3D打印测试

Preparation of Polypropylene Fluorescent Materials and Their 3D Printing Test

通过配位反应合成了三种荧光配合物:铕配合物[Eu(DBM)_(3)phen],8-羟基喹啉铝配合物(AlQ_(3))和8-羟基喹啉锌配合物(ZnQ_(2)),然后通过熔融共混的方式在聚丙烯(PP)材料中分别掺杂这三种荧光配合物,制得三种PP/荧光配合物复合材料,以提高PP发光性能。对这三种复合材料进行了一系列的荧光和力学性能测试。结果表明,三种复合材料都具有良好的发光性能和力学性能,其中当荧光配合物质量分数为0.5%时,PP/Eu(DBM)_(3)phen复合材料在测试条件下的力学性能最优,缺口冲击强度比纯PP提高11%,其最大发射峰位于610 nm处,半峰宽为9 nm。最后应用3D打印机通过熔融沉积成型工艺对复合材料进行打印,所得到的打印模型外观良好,表明此复合材料可适用于3D打印。

Three fluorescent complexes were synthesized through coordination reaction,which were Eu complex[Eu(DBM)_(3)phen],8-hydroxyquinoline aluminum complex(AlQ_(3))and 8-hydroxyquinoline zinc complex(ZnQ_(2)).The three fluorescent complexes were doped on polypropylene(PP)by melt blending to prepare three PP/fluorescent complex composites to improve the luminescence properties of PP.Fluorescent and mechanical properties tests were also carried out on these composites.The results show that these composites have good luminescence and mechanical properties.When 0.5wt%fluorescent complex is doped,PP/Eu(DBM)_(3)phen composite has the best properties under the test conditions,the notched impact strength is increased by 11%compared with neat PP,and the composite has a maximum emission peak at about 610 nm,the full width at half maxima of the composite is 9 nm.Finally,the melt deposition molding of the composite were carried out by using 3D printer,the printed model has the nice appearance,which shows that this composite is suitable for 3D printing.
