我们报告了使用超支化聚合物（HBPs）作为移动的有机纳米粒子掺杂在甲基丙烯酸酯光聚合物的高效体全息记录。合成了两种平均粒径为10 nm的还原型HBPs。实验结果表明，该体系在绿色（532 nm）波长处的衍射效率接近100%，并具有明显的聚合收缩抑制作用。还观察到全息曝光下HBP的周期性聚集。
We report on the use of hyperbranched polymers (HBPs) acting as mobile organic nanoparticles doped in methacrylate photopolymers for highly efficient volume holographic recording. Two types of reduced HBPs having the average size of 10nm are synthesized. The diffraction efficiency near 100% in the green (532nm) and substantive polymerization-shrinkage suppression in this photopolymer system are demonstrated. Periodic assembly of HBPs under holographic exposure is also observed.
