【摘要】 通过紫外光接枝聚合反应 ,将丙烯酸 (AA)接枝于PE膜表面 ,在一定 pH值条件下 ,使接枝膜与Eu3+、α 噻吩甲酰三氟丙酮 (TTA)的乙醇 水溶液或Tb3+、乙酰丙酮 (AcAc)的氯仿 水溶液作用 ,制得红色或绿色荧光膜。与相应的Eu(TTA) 3·(H2 O) 2 或Tb(AcAc) 3·(H2 O) 2 固态配合物相比 ,荧光膜的激发和发射光谱都发生了明显的变化 ,可以推测 ,稀土配合物与高分子材料之间发生了化学键结合。此外 ,还对荧光膜的红外光谱进行了观察。

【Abstract】 The acrylic acid (AA) was grafted onto the PE film surface through UV photograft polymerization.With certain pH value,the grafted films were made to react with the alcohol-water solution of Eu 3+ and α-thenoyltrifluoroacetone (TTA) or with the chloroform-water solution of Tb 3+ and acetyl actone (AcAc),thus causing the preparation of the red or green fluorescent films.As compared with the corresponding Eu(TTA) 3·(H 2O) 2 or Tb(AcAc) 3·(H 2O) 2 solid complexes,both the excitation and emission spectra of the fluorescent films changed remarkably.It′s predictable that chemical bond combination has occured between the rare earth complexes and the macromolecular material.In addition,the IR spectra of the fluorescent films were also observed.
