摘要
研究了一种基于双化学反应体系的绿敏环氧树脂基光致聚合物全息存储材料。通过合理设计并优化双化学反应体系中的低折射率环氧树脂基体体系和高折射率写入单体体系,获得了高透光性的光聚物薄膜,且当薄膜厚度为219μm时,获得了84.3%的衍射效率,5.74×10-3cm2/mJ的感光灵敏度,8.69×10-4的折射率调制度和低至0.32%的缩皱率。最后使用该材料进行了反射式全息图的拍摄,结果表明该材料具有高达5 000 lp/mm以上的分辨率。
A green laser-sensitized epoxy resin photopolymer holographic storage material based on a two-chemistry system is prepared. The high optical transparency of photopolymer film is got by designing low refractive epoxy resin matrix system and high refractive write-in monomer system properly. When film thickness is 219 μm, the maximum diffraction efficiency is 84.3% , the sensitivity is 5.74×10-3cm2/mJ, the maximum refractive index modulation is 8.69×10-4, and volume shrinkage is 0.32%. An experiment was demonstrated, in which the epoxy resin photopolymer material was used as the shooting of a reflection hologram on coin. It indicates that such material has a resolution of up to 5 000 lp/mm.
