报道了一种以丙烯酰胺为单体的光致聚合物材料。通过对组成材料的三乙醇胺 (TEA)、丙烯酰胺 (AA)和亚甲基双丙烯酰胺 (BAA)浓度的优化实验发现 ,三乙醇胺浓度有一个最佳值 ,当保持亚甲基双丙烯酰胺与丙烯酰胺的浓度比为 1∶6时 ,材料中丙烯酰胺的浓度达到 0 .2 5mol/L后 ,衍射效率便达到最大值。材料的灵敏度随着丙烯酰胺的增加而不断地提高。在光聚物介质上能够记录信噪比较高的图像 ,说明该材料适合于大容量体全息存储。
Reported a kind of acrylamide monomer photopolymer material. Optimum concentration of TEA, acrylamide (AA) and methylene bisacrylamide (BAA) in the composites has found that the concentration of triethanolamine has an optimum value. When the concentration of methylene bisacrylamide and When the concentration ratio of acrylamide is 1: 6, the diffraction efficiency reaches the maximum after the concentration of acrylamide reaches 0.52 mol / L. The sensitivity of the material increases with the increase of acrylamide. The ability to record high signal-to-noise images on photopolymer media indicates that the material is suitable for bulk holographic storage.
