| 摘 要： | 本文研究了薄膜型光致聚合物材料中双单体(2-苯氧基乙基丙烯酸酯和N-乙烯基咔唑)的不同配比对材料聚合效率的影响.用红外光谱测定了双组分单体在固体薄膜中光反应条件下的竟聚率,分析了双组分单体在全息记录过程中的聚合情况.针对同一点多角度复用的大容量存储要求,提出了双单体薄膜型光致聚合物的理想模型.初步测定了不同摩尔配比条件下材料的全息存储性能,分析了其中的影响因素.

| Abstract: | The effect of molar ratio of dual monomers,2-phenoxyethyl acrylate(POEA) and N-vinyl carbazole(NVC),on polymerization efficiency of photopolymers for holographic storage was investigated.Through monitoring the relative change of the double bond absorption of samples in FTIR spectra versus exposure time,the reactivity ratio of two monomers in solid films was determined and the polymerization mechanism was discussed.For satisfying the requirement of angle-multiplexed holographic storage,a prefect photopolymer model was supposed.Holographic properties of a series of samples with different molar ratio of dual monomers were measured and analysed. |
