Abstract

Holographic media with high diffraction efficiency are crucial for advancing high-density polarization holographic storage technologies. In this study, we enhanced the holographic performance of the material by exploiting the interaction between C₆₀ and the photoinitiator, and adjusting the cross-linking density between low-refractive-index monomer and high-refractive-index epoxy resin. The results show that increasing the number of functional groups of the monomer can accelerate the polymerization reaction. Furthermore, when synergistically combined with C₆₀ nanoparticles, this increases the diffraction efficiency of the photopolymer to 81.5% and optimizes its polarization holographic response (9.4 %), achieving high photosensitivity and low volume shrinkage (0.0795 %). In large-angle polarization holography, the orthogonal polarization diffraction efficiency of the photopolymer exhibits a strong correlation with C₆₀ nanoparticle doping concentration. The π-π non-covalent interaction between C₆₀ nanoparticles attracts photosensitizers, accelerating the decomposition of the photosensitizer and enhancing the monomer's double-bond conversion. The synthesized photopolymer can achieve high-density storage with a low bit error rate (0.8 %). Aging experiments indicate that this material can remain stable for a long time. This study provides a feasible approach for the development of high-performance nanocomposite photopolymers and materials sensitive to polarization holography.

掺杂C60纳米颗粒光敏聚合物的高密度偏振全息存储优化

高衍射效率的全息介质是推进高密度偏振全息存储技术的关键。在本研究中，我们通过利用C60与光引发剂的相互作用，以及调节低折射率单体与高折射率环氧树脂之间的交联密度来增强材料的全息性能。结果表明，增加单体官能团的数量可以加速聚合反应。此外，当与C60纳米粒子协同作用时，光聚合物的衍射效率提高到81.5%，偏振全息响应优化到9.4%，实现了高光敏性和低体积收缩率（0.0795%）。在大角度偏振全息中，光聚合物的正交偏振衍射效率与C60纳米颗粒掺杂浓度有很强的相关性。C60纳米颗粒之间的π-π非共价相互作用吸引光敏剂，加速光敏剂的分解，增强单体的双键转化。所合成的光聚合物可以实现高密度存储，误码率低（0.8%）。老化实验表明，该材料能长时间保持稳定。本研究为开发高性能的纳米复合光聚合物和偏振全息敏感材料提供了一条可行的途径。
