We present a photopolymeric multifunctional dendrimer for holographic applications. In this study, we described a synthesis of multiphotoreactive dendrimer and phase compatible polymer matrix as well as a numerical simulation of the dendrimer. This holographic photopolymer containing a nanosized photoreactive organic dendrimer could address the aggregation issue of conventional inorganic nanoparticle additives and allowed writing-induced shrinkage to be successfully reduced to the extent of acceptable values for 130 μm thick film. In this report, holographic performance including diffraction efficiency (DE), transmission, photosensitivity, modulation of refractive index, polarization sensitivity, and volume shrinkage has been discussed. The page-wise recording by using an amplitude spatial light modulator (SLM) was also demonstrated.
我们提出了一种用于全息应用的光聚合多功能树状大分子。在这项研究中，我们描述了多光反应性树状大分子和相兼容聚合物基质的合成，以及树状大分子的数值模拟。这种含有纳米尺寸光反应性有机树状大分子的全息光致聚合物可以解决传统无机纳米颗粒添加剂的聚集问题，并成功地将写入诱导的收缩减小到可接受的 130μm 厚膜的程度。在本报告中，讨论了全息性能，包括衍射效率 (DE)、透过率、光敏度、折射率调制、偏振灵敏度和体积收缩。还展示了使用振幅空间光调制器 (SLM) 的逐页记录。
