摘要体全息存储技术以其存储密度高、存储容量大、数据传输速率高、数据搜索时间短等 优势成为一种颇具潜力的海量信息存储技术。但是,高密度全息存储设备迟迟未能商品 化,主要原因是应用于全息存储的材料在某些方面存在缺陷。Resin/Epoxy(环氧树脂)-Irgacure-784 光致聚合物材料作为一种新型的混杂型材料表现出了高折射性能,低损 耗,低膨胀与收缩率,以及较长的存储寿命,在业界引起了广泛的兴趣,然而其内部的 结构,反应机理、物种间的相互作用以及其光/电特性形成的原因和影响却鲜有报道。本 文中,我们在光照条件下通过对该材料内部光化学反应研究的基础上建立了理论模型, 以此探究其反应机理。利用该模型我们将仿真结果与实验数据进行了拟合,并在此基础 上提出了一些的结论。74305

Title Study of Irgacure 784 in an epoxy resin photopolymer
Abstract Volume holographic storage technology with the advantage of its high storage density, large storage capacity, high speed of data transmission, data search time short become a considerable potential of the massive information storage technology。 However, high density holographic storage device delay is not commercialization, because the main reason is application in holographic storage material in some respects flawed。 Resin/Epoxy (epoxy resin) -Irgacure 784 photoinduced polymer materials as a novel hybrid materials exhibit high refractive properties, low loss, low expansion and contraction rate, and longer storage life, in the industry caused widespread interest。 However, its internal structure, reaction mechanism, species interactions and the optical / electrical characteristics of formation cause and effect are rarely reported。 In this paper, we set up a theoretical model based on the study of the photochemical reaction of the material under the condition of light, and then explore the mechanism of the reaction。 By using this model, the simulation results and the experimental data are fitted, and some conclusions are put forward。
